protected Hit < V > [ ] matchExact ( final Hit < V > [ ] hits , final String query ) { throw new UnsupportedOperationException ( ) ; }
subclasses can override this method to do exact match processing . this involves materializing the hits into their original text values and checking for the query string in the materialized value . not possible from the base class . the value - centric rdf version can use the lexicon to materialize the hits and check them for exact match .
