[hibernate-dev] SearchFactory API exposes Class type for entity

[Sanne Grinovero]

When I started refactoring the Search code towards free-form I simply
started to remove all references to Class and replace them with
TypeIdentifier, essentially working only on hibernate-search-engine
and closing the ORM integration modules which don't need to be
affected.

The SearchFactory interface however is meant as public API and exposes
Class in its signatures to identify specific entity types (I'll use
"entity" in its conceptual meaning): for example we have

    void optimize(Class entityType);

Since not only Hibernate Search / ORM will be using Class &
annotations, I could split out the SearchFactory and its default
"class to index mapping" strategies into a separate module, or I could
just keep it there: public API but ignored in case of different
integrations?

I think I'll leave it there for now, but early comments are welcome.
