[jira] Updated: (LUCENE-1790) Add Boosting Function Term Query and
Some Payload Query refactorings
[ https://issues.apache.org/jira/browse/LUCENE-1790?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
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.
Also add marker interface to indicate PayloadQuery types. Refactor Similarity.scorePayload to also take in the doc id.
