--------------------------------------------

Thank you!

I think we should also backport to 3.x?

> 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.
