CompassHits
public interface CompassHits extends CompassHitsOperations(Code)
Holds hits returned from a search performed by compass. Can be used within a transaction context. For hits to be used outside of a transactional context, the CompassHits.detach() and CompassHits.detach(int,int) can be used.

Also allows for highlighting using CompassHits.highlighter(int) , and any highlighting operation (that returns a single String) will be cached within the hits (and also moved to the detached hits, if CompassHits.detach(int,int) is called), and can be used by CompassHitsOperations.highlightedText(int) .
