I need to understand how to create a search that spans multiple entities based on values that may or may not be entered on the ui

e.g.

input value=#{a.name}
input value=#{b.name}

return ( ( FullTextEntityManager ) em ).createFullTextQuery( luceneQuery, a.class, b.class, c.class );

Hi,

maybe looking at one of the test classes will help:http://fisheye.jboss.org/browse/Hibernate/search/trunk/src/test/org/hibernate/search/test/query/LuceneQueryTest.java?r=12908.

Basically the idea is the following:

Code:

Query query = parser.parse( "name:foo");
FullTextQuery hibQuery = s.createFullTextQuery( query, a.class, b.class );
List result = hibQuery.list();

The result list will contains instances of class a and b. You will have to code accordingly.
