Experimental and beta APIs

The PHP client offers also experimental and beta APIs for {es}.

The {es} APIs are marked using the following convention:

Stable APIs should be safe to use extensively in production. Any breaking changes to these APIs should only occur in major versions and will be documented in the breaking changes documentation for that release.
Beta APIs are on track to become stable and permanent features. Use them with caution because it is possible that breaking changes are made to these APIs in a minor version.
Experimental APIs are just that - an experiment. An experimental API might have breaking changes in any future version, or it might even be removed entirely.

All the experimental and beta APIs are marked with a @note tag in the phpdoc section of the code.

The experimental APIs included in the current version of elasticsearch-php are:

$client = ClientBuilder::create()->build();
$params = [
    // ...
];
$result = $client->rankEval($params);

$client = ClientBuilder::create()->build();
$params = [
    // ...
];
$result = $client->scriptsPainlessExecute($params);

Returns all script contexts.

$client = ClientBuilder::create()->build();

$result = $client->getScriptContext();

Returns available script types, languages and contexts.

$client = ClientBuilder::create()->build();

$result = $client->getScriptLanguages();

There are no beta APIs in the current version of elasticsearch-php.
