Hello Marcel,
thank you very much for the solution. Do you have an idea, when joins
will be supported in the JQOM2LuceneQueryBuilder ?

Benjamin

Hi Benjamin,
the QueryObjectModel in jackrabbit is work in progress and not usable in
it's current state.
the equivalent JQOM to your query would be:
qf.createQuery(
qf.join(
qf.selector("nt:file", "f"),
qf.selector("nt:resource", "r"),
qf.JOIN_TYPE_INNER,
qf.sameNodeJoinCondition("r", "f", "jcr:content")),
qf.fullTextSearch("r", null, "Test"),
null,
new Column[] { qf.column("f", null, null) }));

Hello,
I am already testing with your JSR283 QueryObjectModel implementation
and have a question regarding the proper usage.
The XPATH query, which I try to implement with the JQOM is:
//element(*,nt:file)[jcr:contains(jcr:content,'Test')]
Internally it results in a Lucene query:
+(_:PROPERTIES:3:primaryType?4:file _:PROPERTIES:3:primaryType?12:file
_:PROPERTIES:3:primaryType?12:symLink) +ParentAxisQuery
while the ParentAxisQuery is:
+_:LABEL:3:content +_:FULLTEXT:test
With this I get some results.
Now I am trying to build this same query with the QueryObjectModel.
What I do is:
qf.createQuery(qf.selector("nt:file"), qf.fullTextSearch(*null*,
'Test'), *null*, *null*);
The resulting query looks like this:
+(_:PROPERTIES:3:primaryType?4:file _:PROPERTIES:3:primaryType?12:file
_:PROPERTIES:3:primaryType?12:symLink) +_:FULLTEXT:test
With this I get no results.
The JSR-283 documentation says for FullTextSearch:
If *propertyName *is specified, the full-text search scope is the
property of that name on the *selectorName *node in the node-tuple;
otherwise the full-text search scope is all properties of the
*selectorName *node (or, in some implementations, all properties in
the node subtree).
It looks like in the current implementation Jackrabbit is not
searching through the subtree nodes, but anyway this will be
implementation specific.
What is the proper way to create a query with the JQOM, which will run
on all implementations and where the FullTextSearch will look in all
the subtree nodes? I would also like to extend this query by looking
in the filename, so I would always like to return nt:file nodes.
Regards,
Benjamin
