Mark Miller commented on LUCENE-794:
------------------------------------

I have a patch coming tonight. It fixes a few odd mistakes and has a little more documentation.
I had wanted to subpackage it into spanscorer for now, but it appears I can't make a patch
with a new folder so that is out. Should I merge my package.html documentation with the one
currently in highlighter? Also, I am not sure how a contrib that depends on another contrib
should work build file wise (SpanScorer depends on MemoryIndex). I just made up something
that works for now.

This new patch will be off the trunk so now the RangeQuery test fails as it does with the
original QueryScorer...you cannot highlight a constantrangequery to my knowledge.

You also cannot ignore the fields in the query as you can with QueryScorer so that test fails.
The only way that I can see doing this is to have the option in your query parser of ignoring
all fields and just using one field name during parsing. Send the field-normal Query to search,
and then make a field-neutered query for highlighting. That is the approach I will be taking
with my query parser. I sure wish there was something better though.

Ill post the patch when I get out of work.
