Root object person.getPerson seems to not work properly

[ghost]

Hello everybody!

I'm writing to get some help or some idea about why something is happening in my Alfresco Content Service environment. I have built some extensions over my instance using Javascript based Webscripts. All of them work perfectly, however I do have one exception. The problem is: in one webscript I invoke the Javascript root object person.getPerson in this way:

 var userNodes = people.getPeople(null,0);

And it doesn't return anything, however, I do have some users registered in my instance. Also, I can see all of them using the node browser and the following Alfresco-CMIS query:

 SELECT * FROM cm:person

I tried to test the same webscript in a test instance and it worked without problems. So, I don't think the code is the problem. In addition, I have read the implementation of the root object. And I discover that, "under the hoods", the code creates the following FTS query and passes it to the SearchService:
TYPE:"{http://www.alfresco.org/model/content/1.0}person" AND ("***")

I tried to verify this query in the node browser too and it didn't return anything too. I also tried to remove the "AND ("***")" snippet from the query and then it worked without any problems.
Do someone knows what could be and why the query without "AND ("***")" works properly?

Some informations about my environment:
Alfresco's version: 6.2
Edition: Community

Thanks in advance!

The reason for this can very well be that your Search Service / SOLR is not correctly indexing or searching person nodes. This is the reason why there is a difference in behaviour between just using TYPE and TYPE combined with the * wildcard. The latter will use SOLR to query, the former will go directly to the database.
There can also be issues with localised indexation/querying. Apart from a few pre-defined properties, any text property is indexed only for the locale that the node was created in. When you do a query as a user, you may have a different locale in your request context, and your search might not match in SOLR because of that. I have encountered such issues when a background job on the server was synchronising LDAP users using the English server locale, and me - a German admin user - was trying to search for any of them, not getting any results back. This can be solved by enabling cross-locale search in Search Services / SOLR via the shared.properties. I have done a presentation at an Alfresco conference in the past about cross-locale issues in Search Services, which may be of interest here: https://de.slideshare.net/slideshow/important-workarounds-for-making-ass-multilingual/87303198
