I started to implement a Hibernate / Lucene based solution and would like to switch to Hibernate Search now. It is tempting to only work with Hibernate mapped objects and dropping the low level Lucene Document mapping etc.

However, I have a problem with sorting. I used custom Lucene sorting by passing a Sort instance together with the Lucene Query to the IndexSearcher:

is.search(query, sort);

It seems that with Hibernate Search I can only pass a Lucene query to the FulltextSession:

fullTextSession.createFullTextQuery(query);

How do I do sorting in this case?

If I cannot use Lucene sorting, is there a way to use Hibernate? In HQL I can specify 'order by' clauses. Is there a way an additional 'order by' clause? Currently my search looks like this:

FullTextSession fullTextSession = Search.createFullTextSession(session);
org.hibernate.Query fullTextQuery = fullTextSession.createFullTextQuery(query);
fullTextQuery.list();

What shall I do? Any help appreciated :)

This is not yet possible, but I want to focus on queries for the next release.

that would be awesome if you had time to contribute this feature :-)

Is the order by in Hibernate Search is now supported ?

Yes it is :)
Since 3.0.0.beta2. The current release is 3.0.0.beta3.

Thank you, I will try ;)

is it possible to specify ASC ou DESC order ?

Sorting is the same as in Lucene.

I use :

But I don't know how to invert the order of the results.

Use the Sort(String field, boolean reverse) constructor.

Thank you very much ;)
