wrong Similarity used when sharing index among entities
-------------------------------------------------------

                 Key: HSEARCH-271
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HSEARCH-271
             Project: Hibernate Search
          Issue Type: Bug
          Components: engine
    Affects Versions: 3.1.0.Beta1
            Reporter: Sanne Grinovero


When the same IndexWriter is used during a transaction commit for two or more entities (sharing the same index) but having different Similarities,
the Similarity used is the one from the first entity to be indexed.
No warning is logged and it's hard to recognize without being a paranoid Similarity expert...

If the two Entities share an object hierarchy, then Search correctly throws an exception during startup.

Should we throw an exception also on index sharing or solve it to support different Similarities even on different obejcts being part of same tree? (to be consistent)
