I think this ticket is about the same as https://hibernate.atlassian.net/browse/HSEARCH-175#icft=HSEARCH-175 , though with a bit less details.
I'll close this ticket for now, feel free to reopen it if you think it's fundamentally different from HSEARCH-175.

no, I mean some kind of stereotypes

@FieldBridge(impl=WordPOIFieldBridge.class, params()=...)
public @interface WordBridge {
}

But this concept needs more refinement

FieldBridge exists by now.
