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.
