OK, I need to take a step back, Michael, b/c I thought I understood
your original comment, but I went to make the change and am no longer
sure.
By "first term position" are you referring to multiple terms per
position or do you mean the same term in different positions? When I
implemented the BTQ (BoostingTermQuery) I modeled it pretty much off
of the SpanTermQuery (STQ) which I felt had very similar
functionality, other than having to load the payload.
Doesn't the next() method on the BoostingSpanScorer take care of
moving through the various positions that the term appears at,
whereupon it loads the payload at the position? Could you write up a
patch to the test to demonstrate?
Thanks,
Grant

Hi Grant,
cool that you started implementing queries that use of payloads! I
have a question about this one: BoostingTermQuery only takes the
payload of the first term position into account for scoring. Could
you explain why you implemented it this way? Shouldn't we rather
compute the average of the payload values of all positions?
Payload Queries

Key: LUCENE-834
URL: https://issues.apache.org/jira/browse/LUCENE-834
Project: Lucene - Java
Issue Type: New Feature
Components: Search
Reporter: Grant Ingersoll
Assigned To: Grant Ingersoll
Priority: Minor
Attachments: boosting.term.query.patch
Now that payloads have been implemented, it will be good to make
them searchable via one or more Query mechanisms. See http://
wiki.apache.org/lucene-java/Payload_Planning for some background
information and https://issues.apache.org/jira/browse/LUCENE-755
for the issue that started it all.
