Class PayloadTermQuery

This class is very similar to SpanTermQuery except that it factors in the value of the payload located at each of the positions where the Term occurs.

NOTE: In order to take advantage of this with the default scoring implementation (DefaultSimilarity), you must override ScorePayload(Int32, Int32, Int32, BytesRef), which returns 1 by default.

Payload scores are aggregated using a pluggable PayloadFunction.
