Grant Ingersoll updated LUCENE-834:
-----------------------------------
Attachment: boosting.term.query.patch
First draft at a BoostingTermQuery, which is based on the SpanTermQuery and can be used for boosting the score of a term based on what is in the payload (for things like weighting terms higher according to their font size or part of speech).
A couple of classes that were previously package level are now public and have
been marked as Public and for derivational purposes only.
See the CHANGES.xml for some more details.
I believe all tests still pass.
Grant,
This is great stuff! I know quite a few projects that will love this -
specifically to boost terms differently based on a POS tag.
We had a discussion recently in Nutch about changing the way typical
Nutch queries are translated into Lucene queries, and performance
implications there. If you're looking for a challenge ;) could you
perhaps take a look at this discussion and see if you could contribute
something? ;)

Thanks in advance!
