======================================

This API connector is intended to be used with PHP 5 (any version >= 5.3) and Composer. It is based on the V2 API of OpenSearchServer.

Setup

  • Create a folder for your project
mkdir ossphp_sandbox
cd ossphp_sandbox
  • Create a file named composer.json with this content:
{
    "require": {
        "opensearchserver/opensearchserver": "3.0.*"
    }
}
  • Run these commands to install vendors:
curl -sS https://getcomposer.org/installer | php
php composer.phar install
  • Create a folder where example code can be written:
mkdir web
cd web
echo "<?php require_once '../vendor/autoload.php';" > index.php
  • Code can now be written in file web/index.php. Take examples from vendor/opensearchserver/opensearchserver/examples/oss_examples.php.

Quick start

A global handler must be created. It will be used to submit every request to your OpenSearchServer instance:

$url        = '<instance URL>';
$app_key    = '<API key>';
$login      = '<login>';
$oss_api = new OpenSearchServer\Handler(array('url' => $url, 'key' => $app_key, 'login' => $login));

Each API request is wrapped in a particular class. Requests must be instanciated, configured and then passed to $oss_api->submit() that will return an OpenSearchServer\Response object.

Create an index

This code creates an index based on our "WEB_CRAWLER" template, which will automatically create a schema allowing to easily crawl a website.

$request = new OpenSearchServer\Index\Create();
$request->index('first_index')->template(OpenSearchServer\Request::TEMPLATE_WEB_CRAWLER);
$response = $oss_api->submit($request);

Configure web crawler

Add some allowed patterns:

$request = new OpenSearchServer\Crawler\Web\Patterns\Inclusion\Insert();
$request->index('first_index')
        ->patterns('http://www.my-website.com/*', 'http://www.your-website.net/*');
$oss_api->submit($request);

Note character *: it means crawler will be allowed to follow any URL starting by these patterns.

Add some start URLs for crawler:

$request = new OpenSearchServer\Crawler\Web\Url\Insert();
$request->index('first_index')
        ->urls('http://www.my-website.com', 'http://www.your-website.net');
$oss_api->submit($request);

Here * is not used since real URL are given to crawler: it will use these URLs as first entry points.

Start crawler:

$request = new OpenSearchServer\Crawler\Web\Start();
$request->index('first_index');
$oss_api->submit($request);

Index documents

While crawler is running some documents can still be manually indexed:

$document = new OpenSearchServer\Document\Document();
$document   ->lang(OpenSearchServer\Request::LANG_FR)
            ->field('title','The Count Of Monte Cristo')
            ->field('url', '1');

$document2 = new OpenSearchServer\Document\Document();
$document2  ->lang(OpenSearchServer\Request::LANG_FR)
            ->field('title','The Three Musketeers')
            ->field('url', '2');

$request = new OpenSearchServer\Document\Put();
$request->index('first_index')
        ->addDocuments(array($document, $document2));
$oss_api->submit($request);

Here objects of type OpenSearchServer\Document\Document() are being used to create documents, but some other options exist: passing array, passing JSON, ... See documentation below to know all about this.

Search:

It is quite easy then to search for documents:

$request = new OpenSearchServer\Search\Field\Search();
$request->index('first_index')
        ->query('The Count')
        ->searchField('title')
        ->returnedFields('title');
$results = $oss_api->submit($request);

echo 'Total number of results: ' . $results->getTotalNumberFound() . '<br/>';
echo 'Number of results in this set of results: ' . $results->getNumberOfResults();

foreach($results as $key => $result) {
    echo '<hr/>Result #'.$key.': <br/>';
    echo '<li>Title: '.$result->getField('title').'</li>';
    echo '</ul>';
}

How to make requests

In this PHP client requests to OpenSearchServer's API are objects. Each request object must be submitted to a global handler that is in charge of sending them to an OpenSearchServer instance and returning a response.

Create an handler

$url        = '<instance URL>';
$app_key    = '<API key>';
$login      = '<login>';
$oss_api = new OpenSearchServer\Handler(array('url' => $url, 'key' => $app_key, 'login' => $login));

Create a request

Several types of objects are available, each being a mapping to one API. For instance objects of type OpenSearchServer\Index\Create will be used to create index and objects of type OpenSearchServer\Search\Field\Search will be used to search for documents.

Each request object is a child of the abstract parent class OpenSearchServer\Request.

For example here is the code to create a request that wil create an index when sent to an OpenSearchServer instance:

$request = new OpenSearchServer\Index\Create();

After being created each type of request must be configured in a particular way, depending on its type, by calling some methods.

For example this code will tell OpenSearchServer to name the new index "first_index":

$request->index('first_index');

Important note:

  • method index() is really important and is shared by almost every type of requests. In the case of index creation it serves to give a name to new index and in almost every other request it will be used to configure the index on which API call must be made.

This method will not be documented further but will be displayed in code examples when needed.

Once configured request must be sent to an OpenSearchServer instance thanks to the handler created before:

$response = $oss_api->submit($request);

Create request by using an array of JSON parameters

JSON body of request can be given as an array of JSON parameters to the constructor. If values are given this way every data set by calling specific methods on this request will be ignored.

However some methods must still be called to set index on which work and every parameters used directly in request's URL.

Example: create a Search field template:

$json = array();
$json['query'] = "test with values";
$json['searchFields'] = array(
    array(
        "field" => "title",
        "mode" => "PHRASE",
        "boost" => 3
    ),
    array(
        "field" => "content",
        "mode" => "PHRASE",
        "boost" => 4
    )
);
$request = new OpenSearchServer\Search\Field\Put($json);
$request->index('00__test_web')
        ->template('test_with_json_values');
$response = $oss_api->submit($request);

Create request by using JSON text

JSON body of request can be given as a JSON strings to the constructor. If values are given this way every data set by calling specific methods on this request or by giving JSON array values will be ignored.

However some methods must still be called to set index on which work and every parameters used directly in request's URL.

Example: create a Search field template:

$json = <<<JSON
{
    "query": "open search server",
    "start": 0,
    "rows": 10,
    "lang": "ENGLISH",
    "operator": "AND",
    "collapsing": {
        "max": 2,
        "mode": "OFF",
        "type": "OPTIMIZED"
    },
    "returnedFields": [
        "url"
    ],
    "snippets": [
        {
            "field": "title",
            "tag": "em",
            "separator": "...",
            "maxSize": 200,
            "maxNumber": 1,
            "fragmenter": "NO"
        },
        {
            "field": "content",
            "tag": "em",
            "separator": "...",
            "maxSize": 200,
            "maxNumber": 1,
           "fragmenter": "SENTENCE"
        }
    ],
    "enableLog": false,
    "searchFields": [
        {
            "field": "title",
            "mode": "PHRASE",
            "boost": 3
        },
        {
            "field": "content",
            "mode": "PHRASE",
            "boost": 4
        },
        {
            "field": "titleExact",
            "mode": "PHRASE",
            "boost": 5
        },
        {
            "field": "contentExact",
            "mode": "PHRASE",
            "boost": 6
        }
    ]
}
JSON;
$request = new OpenSearchServer\Search\Field\Put(null, $json);
$request->index('00__test_web')
        ->template('test_with_json_text');
$response = $oss_api->submit($request);

Handle response and search results

Several types of responses can be returned by submit(). Internally this method uses a Factory that builds a response depending on the type of Request given.

OpenSearchServer\Response\Response

Main Response class.

  • Methods:
    • isSuccess(): true if everything went well, false if there was a problem during execution of request.
    • getInfo(): some requests can return some information. For example Index deleted: 00__test_file.
    • getRawContent(): return raw JSON content of response.
    • getJsonValues(): return an array of values built from JSON response.
  • Example:
$request = new OpenSearchServer\Index\Create();
$request->index('index_name');
$response = $oss_api->submit($request);
print_r($response->isSuccess());

OpenSearchServer\Response\ResponseIterable

Extends OpenSearchServer\Response\Response. Used when response contain iterable values. This class implements \Iterator and can thus be used in a loop structure.

  • Example: loop through suggestions of an autocompletion query:
$request = new OpenSearchServer\Autocompletion\Query();
$request->index('00__test_file')
        ->name('autocomplete')
        ->query('count of')
        ->rows(10);
$response = $oss_api->submit($request);
foreach($response as $key => $item) {
    echo '<br/>Item #'.$key .': ';
    print_r($item);
}
  • Requests that use this type of response:
    • OpenSearchServer\Autocompletion\Query
    • OpenSearchServer\Autocompletion\GetList
    • OpenSearchServer\Crawler\Rest\GetList
    • OpenSearchServer\Index\GetList
    • OpenSearchServer\Field\GetList
    • OpenSearchServer\SearchTemplate\GetList
    • OpenSearchServer\MoreLikeThis\GetList
    • OpenSearchServer\Analyzer\GetList
    • OpenSearchServer\Synonyms\GetList
    • OpenSearchServer\Crawler\Rest\GetList
    • OpenSearchServer\Crawler\Web\Patterns\Exclusion\GetList
    • OpenSearchServer\Crawler\Web\Patterns\Inclusion\GetList
    • OpenSearchServer\Parser\GetList

OpenSearchServer\Response\SearchResult

Extends OpenSearchServer\Response\ResponseIterable. Used for search results.

  • Methods:
    • getResults(): return array of objects of type OpenSearchServer\Response\Result
    • getFacets(): return an array of facets for this query. Each facet is an array with key being name of field and values being array in the form <text value> => <number of occurrences>

Example of array of facets:

Array (size=3)
  'host' => 
    array (size=7)
      'http://www.bbc.com' => int 149
      'http://www.facebook.com' => int 47
  'lang' => 
    array (size=2)
      'en' => int 43
      'es' => int 12
  'contentBaseType' => 
    array (size=2)
      'pdf' => int 9
      'text/html' => int 41
  • getQuery(): return query executed by OpenSearchServer
  • getRows(): return number of rows asked
  • getStart(): return starting offset
  • getTotalNumberFound(): return total number of results found in index for this query
  • getTime(): return query duration, in ms
  • getCollapsedDocCount(): return number of total collapsed docs
  • getMaxScore(): return max score in this results set
  • getNumberOfResults(): return number of results in this results set

Example: this class being iterable it can also be used in a loop structure:

$request = new OpenSearchServer\Search\Field\Search();
$request->index('index_name')
        ->query('house')
        //using a pre-configured query template
        ->template('search');
$results = $oss_api->submit($request);

echo 'Total number of results: ' . $results->getTotalNumberFound() . '<br/>';
echo 'Number of results in this set of results: ' . $results->getNumberOfResults();

foreach($results as $key => $result) {
    echo '<hr/>Result #'.$key.': <br/>';
    print_r($result);
}

This class creates object of type OpenSearchServer\Response\Result:

  • Methods:
    • getPos():
    • getScore():
    • getCollapsedCount():
    • getField($fieldName, $returnFirstValueOnly = true): return value of a field
      • $fieldName is the name of the field to return. $returnFirstValueOnly can be set to false to get every values of a multivalued field. Often fields will have only one value, thus default value for this parameter is true.
    • getSnippet($fieldName, $returnFirstValueOnly = true): return value of a snippet
      • $fieldName is the name of the field from which the snippet has been created. $returnFirstValueOnly can be set to false to get every snippets if several snippets where asked.
    • getAvailableFields($returnAllWithoutValues = false): return all available fields for this result.
      • $returnAllWithoutValues can be set to true to return fields that have been configured as returnedFields in the query even if they have no value for this result.
    • getAvailableSnippets($returnAllWithoutValues = false): return all available snippets for this result.
      • $returnAllWithoutValues can be set to true to return snippets that have been asked the query even if they have no value for this result.
    • getHighlightedSnippets(): return list of all fields for which an higlighted snippet has been made
  • Example:
$request = new OpenSearchServer\Search\Field\Search();
$request->index('index_name')
        ->query('house')
        //using a pre-configured query template
        ->template('search');
$results = $oss_api->submit($request);

echo 'Total number of results: ' . $results->getTotalNumberFound() . '<br/>';
echo 'Number of results in this set of results: ' . $results->getNumberOfResults();

foreach($results as $key => $result) {
    echo '<hr/>Result #'.$key.': <br/>';
    echo 'Available fields:</br>- ';
    echo implode('<br/>- ', $result->getAvailableFields());
    echo '<br/>Available snippets:</br>- ';
    echo implode('<br/>- ', $result->getAvailableSnippets());
    echo '<ul>';
    echo '<li>Title:'.$result->getSnippet('title').'</li>';
    echo '<li>Url:'.$result->getField('url').'</li>';
    echo '</ul>';
}

OpenSearchServer\Response\MoreLikeThisResult

This kind of response looks like OpenSearchServer\Response\SearchResult but with fewer features, since results returned by MoreLikeThis query are simpler.

  • Methods:
    • getResults(): return array of objects of type OpenSearchServer\Response\Result
    • getQuery(): return query

OpenSearchServer\Response\SpellCheckResult

This response is returned by SpellCheck queries. It is used to access spell check suggestions for each asked field.

Example:

$request = new OpenSearchServer\SpellCheck\Search();
$request->index('index_name')
        ->query('houze')
        ->template('spellcheck');
$response = $oss_api->submit($request);
var_dump($response->getBestSpellSuggestion('title'));
var_dump($response->getSpellSuggestionsArray('title'));

Available methods:

  • getSpellSuggestionsArray(string $fieldname): return the spell suggestions for one field as array, key is searched word and value is array of suggestions: key is suggestion and value frequency. Array will be sorted with more frequent suggestions at the beginning.
    • Example of result
  array (size=3)
  'houze' => 
    array (size=2)
      'house' => int 12
      'houzz' => int 6
  • getBestSpellSuggestion(string $fieldname): return best spell suggestion for this field.
  • getSpellSuggest(string $fieldname): helper method, alias to getBestSpellSuggestion().

Work with index

Create an empty index

Go to API documentation for this method

$request = new OpenSearchServer\Index\Create();
$request->index('index_name');
$response = $oss_api->submit($request);

Create an index with a template

Two pre-configured templates are offered with OpenSearchServer: WEB_CRAWLER and FILE_CRAWLER. Each template comes with pre-configured schema, queries, renderers.

Template WEB_CRAWLER:

$request = new OpenSearchServer\Index\Create();
$request->index('00__test_file')->template(OpenSearchServer\Request::TEMPLATE_WEB_CRAWLER);
$response = $oss_api->submit($request);

Template FILE_CRAWLER:

$request = new OpenSearchServer\Index\Create();
$request->index('00__test_file')->template(OpenSearchServer\Request::TEMPLATE_FILE_CRAWLER);
$response = $oss_api->submit($request);

Get list of index on an instance

Go to API documentation for this method

$request = new OpenSearchServer\Index\GetList();
$response = $oss_api->submit($request);
foreach($response as $key => $item) {
    echo '<br/>Item #'.$key .': ';
    print_r($item);
}

This class does not need a call to ->index() before submission.

Delete an index

Go to API documentation for this method

$request = new OpenSearchServer\Index\Delete();
$request->index('index_name');
$response = $oss_api->submit($request);

Check if an index exists

Go to API documentation for this method

$request = new OpenSearchServer\Index\Exists();
$request->index('index_name');
$response = $oss_api->submit($request);

Instance monitoring

Several instance-wide monitoring properties can be retrieved:

$request = new OpenSearchServer\Monitor\Monitor();
$request->full();
$response = $oss_api->submit($request);
echo '<ul>';
foreach($response as $propName => $value) {
    echo '<li>'.$propName.': '.$value.'</li>';
}
echo '</ul>';

This would display for example:

  • availableProcessors: 4
  • freeMemory: 38656976
  • memoryRate: 12.958230285108
  • maxMemory: 1879048192
  • totalMemory: 298319872
  • indexCount: 59
  • freeDiskSpace: 24181137408
  • freeDiskRate: 23.061161199939
  • java.runtime.name: Java(TM) SE Runtime Environment
  • sun.boot.library.path: C:\Program Files\Java\jre7\bin
  • java.vm.version: 24.51-b03
  • java.vm.vendor: Oracle Corporation
  • java.vendor.url: http://java.oracle.com/
  • ...
  • ...

Available methods:

  • full(boolean $full): if set to true return every available properties. Otherwise return only some basic properties.

Configure schema

In OpenSearchServer each index must have a schema. A schema is a list of fields, each with some properties.

Create a field

Go to API documentation for this method

$request = new OpenSearchServer\Field\Create();
$request->index('index_name')
        ->name('titleStandard')
        ->indexed(true)
        ->analyzer('StandardAnalyzer')
        ->stored(true)
        ->copyOf('title');
$response = $oss_api->submit($request);

Available methods:

  • name(string $name): name of field to create.
  • indexed(boolean $indexed): tells whether or not this field must be indexed. Indexed field can then used in full-text searchs.
  • analyzer(string $analyzerName): analyzer to use on this field. Analyzer allow to apply several transformations on indexed or searched data.
  • stored(boolean $stored): tells whether or not this field must be stored. Stored field can return their original values in search queries, even if some Analyzers transformed it.
  • copyOf(string/array $fields): field(s) from which copy value. Value is copied before transformation by analyzers. A string or an array of string can be given to this method.

Create full schema at once

Schema can be totally created at once using some JSON Text or JSON array of values with object of type OpenSearchServer\Field\CreateBulk.

$json = <<<JSON
[
        {
            "name": "uniqueId",
            "indexed": "YES",
            "stored": "NO"
        },
        {
            "name": "title",
            "indexed": "YES",
            "stored": "YES",
            "analyzer": "TextAnalyzer"
        },
        {
            "name": "description",
            "indexed": "YES",
            "stored": "YES",
            "analyzer": "TextAnalyzer"
        },
        {
            "name": "descriptionStandard",
            "indexed": "YES",
            "stored": "NO",
            "analyzer": "StandardAnalyzer",
            "copyOf": [
                "description"
            ]
        }
]
JSON;
$request = new OpenSearchServer\Field\CreateBulk(null, $json);
$request->index('00__test_schema');
$response = $oss_api->submit($request);

Get list of fields

Go to API documentation for this method

$request = new OpenSearchServer\Field\GetList();
$request->index('index_name');
$response = $oss_api->submit($request); 
foreach($response as $key => $item) {
    echo '<br/>Item #'.$key .': ';
    print_r($item);
}

Get details of a specific field

Go to API documentation for this method

$request = new OpenSearchServer\Field\Get();
$request->index('index_name')
        ->name('titleStandard');
$response = $oss_api->submit($request);

Available methods:

  • name(string $name): name of field to get information for.

Delete a field

Go to API documentation for this method

$request = new OpenSearchServer\Field\Delete();
$request->index('index_name')
        ->name('titleStandard');
$response = $oss_api->submit($request);

Available methods:

  • name(string $name): name of field to delete.

Set default and unique field for an index

Go to API documentation for this method

$request = new OpenSearchServer\Field\SetDefaultUnique();
$request->index('index_name')
        ->defaultField('title')
        //remove unique field for this index
        ->uniqueField();
$response = $oss_api->submit($request);

Available methods:

  • defaultField(string $name): name of field that must be used as default field. Default field is used for search queries when no particular field is configured in the query. Empty value removes default field setting.
  • uniqueField(string $name): name of field that must be used as unique field. Unique field is used as a primary key. Empty value removes unique field setting.

Analyzers

Create an analyzer

Go to API documentation for this method

Analyzer can be created or updated using some JSON Text or JSON array of values with object of type OpenSearchServer\Analyzer\Create.

$json = <<<JSON
{
  "queryTokenizer":{"name":"KeywordTokenizer"},
  "indexTokenizer":{"name":"KeywordTokenizer"},
  "filters":[
    {
      "name":"ShingleFilter",
      "properties":{
        "max_shingle_size":"5",
        "token_separator":" ",
        "min_shingle_size":"1"
      },
      "scope":"QUERY_INDEX"
    },
    {
      "name":"PrefixSuffixStopFilter",
      "properties":{
        "prefixList":"English stop words",
        "ignore_case":"true",
        "token_separator":" ",
        "suffixList":"English stop words"

    } 
  ]
}
JSON;
$request = new OpenSearchServer\Analyzer\Create(null, $json);
$request->index('index_name')
        ->name('TestAnalyzer');

Parse files

OpenSearchServer is able to parse files from lots of different types. Parsers allow for extraction of information inside documents.

Methods for this API do not require an index to work with, since parsing is "index-free". Those API do not index any data, they simply parse files and send back parsed data.

List existing parsers

Go to API documentation for this method

$request = new OpenSearchServer\Parser\GetList();
$response = $oss_api->submit($request);
foreach($response as $value) {
    var_dump($value);
}

Get details about a specific parser

Go to API documentation for this method

$request = new OpenSearchServer\Parser\Get();
$request->name('html');
$response = $oss_api->submit($request);
var_dump($response->getJsonValues());
echo 'Information returned by HTML parser:';
var_dump($response->getJsonValues()->fields);

Parse a file by uploading it

Go to API documentation for this method

Use this API to send a file to OpenSearchServer and get back parsed data.

$request = new OpenSearchServer\Parser\Parse\Upload();
$request->name('pdf')
        ->file(__DIR__.'/BookPdf.pdf');
$response = $oss_api->submit($request);
var_dump($response->getJsonValues());

Another way to send the file is by using a particular method of the Handler. This method does not use the Buzz HTTP client but rather directly makes a CURL call, using CurlFile to send the file.

The file path must be given using method filePath() instead of file(), and request must be submitted using submitFile() instead of submit().

This method is more direct and will use less memory than the previous one.

$request = new OpenSearchServer\Parser\Parse\Upload();
$request->name('pdf')
        ->filePath(__DIR__.'/BookPdf.pdf');
$response = $oss_api->submitFile($request);
var_dump($response->getJsonValues());

Parse a file located on the server

Go to API documentation for this method

Use this API to ask OpenSearchServer to parse a file located on its server, and get back parsed data.

$request = new OpenSearchServer\Parser\Parse\Local();
$request->name('pdf')
        ->file('E:/_temp/BookPdf.pdf');
$response = $oss_api->submit($request);
var_dump($response->getJsonValues());

Parse a file and let OpenSearchServer detect its type

Go to API documentation for this method

Use this API to send a file or to parse a file located on the server: OpenSearchServer will try to automatically detect its MIME type to apply the correct parser on it.

$request = new OpenSearchServer\Parser\Parse\DetectType();
$request->path('E:/_temp/report.docx');
$response = $oss_api->submit($request);
var_dump($response);

Available methods:

  • name(string $name): name of the file. Optionnal.
  • type(string $type): type of the file. Optionnal.
  • path(string $path): path of the file located on the server. Optionnal.
  • file(string $fullPath): path of the file to send to the parser. Optionnal.
  • filePath(string $fullPath): path of the file to send to the parser if request is submitted using submitFile(). Optionnal.
  • variable(string $variable, string $value): one property of the parser. Optionnal.

Autocompletion

  • name(string $name): name of autocompletion item to create.
  • field(string $name): name of field in main schema from which suggestion are returned.
  • fields(array $fields):** helper method, calls field() for each item in array.

Build autocompletion

Go to API documentation for this method

Autocompletion sub-index need to be re-built frequently, when content on main index changes. This can be automatized with OpenSearchServer's Schedulers or done by calling this API.

$request = new OpenSearchServer\Autocompletion\Build();
$request->index('index_name')
        ->name('autocomplete');
$response = $oss_api->submit($request);

Available methods:

  • name(string $name): name of autocompletion item to build.

            'value' => '"Very true," said Monte Cristo; "it is unnecessary, we know each other so well!"
"On the contrary," said the count, "we know so little of each other."
"Indeed?" said Monte Cristo, with the same indomitable coolness; "let us see. Are you not the soldier Fernand who deserted on the eve of the battle of Waterloo? Are you not the Lieutenant Fernand who served as guide and spy to the French army in Spain? Are you not the Captain Fernand who betrayed, sold, and murdered his benefactor, Ali? And have not all these Fernands, united, made Lieutenant-General, the Count of Morcerf, peer of France?"
"Oh," cried the general, as if branded with a hot iron, "wretch,—to reproach me with my shame when about, perhaps, to kill me! No, I did not say I was a stranger to you.'

        ->snippet('content', 'b', '...', 200, 1, OpenSearchServer\Search\Search::SNIPPET_SENTENCE_FRAGMENTER);
$results = $oss_api->submit($request);

Available methods:

  • General options:
    • query(string $query): search keywords
    • emptyReturnsAll(boolean $value): if set to true and keywords are empty will return every documents of the index
    • operator(string $operator): Set the default operator: OR or AND
    • lang(string $lang):
    • enableLogs(boolean value): Enale logging of this query
    • returnedFields(array $fields): An array of fieldnames to return with results
    • rows(int $rows):
    • template(string $name): set name of query template to use. If set, query will use given registered query template but will override every parameters defined in the query object.
    • snippet():
  • Sorting options
    • sort(string $field, string $direction): add a sorting on one field. Can be called multiple times to successively sort on different fields.
    • sorts(array $sorts, string $direction): helper method. Calls sort() for each item in array.
  • Scoring options
    • scoring(string $field, int $weight, boolean $ascending, type $type): add one level of scoring.
  • Boosting queries
    • boostingQuery(string $queryPattern, int $boost): add one boosting query.
  • Facetting options
    • facet(string $field, int $min = 0, boolean $multi = false, boolean $postCollapsing = false): compute facet for one field: this will return count of every different values for this field. Facets can be used through ->getFacets() when workingh with an OpenSearchServer\Response\SearchResult object. You can find more details in the proper section.
  • Filtering options
    • queryFilter(string $filter): add a filter with a pattern query. For example : lang:en.
    • negativeFilter(string $filter): add a negative query filter.
    • geoFilter(string $shape, string $unit, int $distance): add a geo filter.

    • relativeDateFilter(string $field, string $fromUnit, int $fromInterval, string $toUnit, int $toInterval, string $dateFormat, boolean $isNegative):: add a RelativeDateFilter. This filter allows dynamic date filtering.
      • This filter can be used to simplify date filtering, or when saving a Search template. If a template is saved with a relative date filter it will always force a date filter base on current date. For example if set with values fromUnit = days, fromInterval = 30, toUnit = days, toInterval = 0 and dateFormat = yyyyMMdd this search template will always filter documents whose chosen filtered field contains a date in last 30 days. For instance if $field is "fileSystemDate" and if a search is run on february 1st of 2014 it will translates to this filter: fileSystemDate:[20140101 TO 20140201].
