Subject [jira] Updated: (LUCENE-1790) Boosting Function Term Query
Date Fri, 07 Aug 2009 15:17:14 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.  (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)
