How to build lucene query with OR using search context?

anujs86 — Mon, 08 Oct 2012 11:48:59 GMT

In Search Context there is a method addAttributeQuery(QName qname, String value).This creates search query with AND.Is there any way I can add OR query in search context?Suppose I have one property test1:name and another attribute test2:name.I want to search name property with respect to test1:name

You need to use the SearchParameter object and SearchService if you are using JAVA.
Also for javascript you need to user the SearchService.

In Search Context there is a method addAttributeQuery(QName qname, String value).
This creates search query with AND.

Is there any way I can add OR query in search context?

Suppose I have one property test1:name and another attribute test2:name.
I want to search name property with respect to test1:name as well as test2:name.

I can do it by writing lucene query and get the results. But I have to do it via Search Context.

Let me know if its possible as i do not see any method in SearchContext.java to take OR query.

Anyone has any idea??

Hi,
look here for info about SearchService http://docs.alfresco.com/4.0/index.jsp?topic=%2Fcom.alfresco.enterprise.doc%2Fconcepts%2Frm-searchsyntax-APIs.html
You can define a query using SearchService.LANGUAGE_FTS_ALFRESCO and a template as descibed here http://docs.alfresco.com/4.0/index.jsp?topic=%2Fcom.alfresco.enterprise.doc%2Fconcepts%2Frm-searchsyntax-APIs.html

Regards,
Andrea

Thanks Andrea.

I want information on SearchContext as it has already been used and I cannot change it at this point of time.
I want to know whether we can add OR query using SearchContext.

'OR' condition is being called by default unless 'AND' condition is being called by force.

Check the svn code for SearchContext object at http://svn.alfresco.com/repos/alfresco-open-mirror/alfresco/HEAD/root/projects/web-client/source/java/org/alfresco/web/bean/search/SearchContext.java

   /**
    * @return Returns if AND is forced between text terms. False (OR terms) is the default.
    */
   public boolean getForceAndTerms()
   {
      return this.forceAndTerms;
   }
