Class PayloadNearQuery
java.lang.Object
org.apache.lucene.search.Query
org.apache.lucene.search.spans.SpanQuery
org.apache.lucene.search.spans.SpanNearQuery
org.apache.lucene.search.payloads.PayloadNearQuery
- All Implemented Interfaces:
Cloneable
This class is very similar to
SpanNearQuery
except that it factors
in the value of the payloads located at each of the positions where the
TermSpans
occurs.
NOTE: In order to take advantage of this with the default scoring implementation
(DefaultSimilarity
), you must override DefaultSimilarity.scorePayload(int, int, int, BytesRef)
,
which returns 1 by default.
Payload scores are aggregated using a pluggable PayloadFunction
