Mark Miller updated LUCENE-1790:
--------------------------------
Attachment: LUCENE-1790.patch
remove some unused imports
added missing license header
Added hashCode to BoostingFunctionTermQuery
Added hashCode/equals to PayloadFunction classes
added hashcode/equals to query - really it should be handling the
equals/hashcode for boost, not subclasses (which will be likely to forget it -
you should check super classes for these things anyway as well).
BoostingFunctionTermQuery is a subclass of SpanTermQuery, but both of them use
a weak equals method (using instanceof)
so while BoostingFunctionTermQuery.equals(SpanTermQuery) should equal
SpanTermQuery.equals(BoostFunctionTermQuery), it doesn't.
Added new hashCode/equals for both classes that work properly.
Added a couple tests for these fixes
> Add Boosting Function Term Query and Some Payload Query refactorings

> 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.
> Also add marker interface to indicate PayloadQuery types. Refactor
> Similarity.scorePayload to also take in the doc id.
