Grant Ingersoll updated LUCENE-1790:
------------------------------------
Description: Similar to the BoostingTermQuery, the
BoostingFunctionTermQuery is a SpanTermQuery, but the difference is the payload
score for a doc is not the average of all the payloads, but applies a function
to them instead. BoostingTermQuery becomes a BoostingFunctionTermQuery with an
AveragePayloadFunction applied to it. (was: Similar to the BoostingTermQuery,
the BoostingMaxTermQuery is a SpanTermQuery, but the difference is the payload
score for a doc is not the average of all the payloads, but the maximum
instead.)
Summary: Boosting Function Term Query (was: Boosting Max Term Query)
