      Description

      The ability to gather more details than just the score, of how a given
      doc matches the current query, has come up a number of times on the
      user's lists. (most recently in the thread "Query Match Count" by
      Ryan McV on java-user).

      EG if you have a simple TermQuery "foo", on each hit you'd like to
      know how many times "foo" occurred in that doc; or a BooleanQuery +foo
      +bar, being able to separately see the freq of foo and bar for the
      current hit.

      Lucene doesn't make this possible today, which is a shame because
      Lucene in fact does compute exactly this information; it's just not
      accessible from the Collector.
