Subject [jira] Updated: (LUCENE-1790) Add Boosting Function Term Query and Some Payload Query refactorings
Date Fri, 07 Aug 2009 20:35:14 GMT

     [ 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.
