Class	Description
AveragePayloadFunction	Calculate the final score as the average score of all payloads seen.
MaxPayloadFunction	Returns the maximum payload score seen, else 1 if there are no payloads on the doc.
MinPayloadFunction	Calculates the minimum payload seen
PayloadFunction	An abstract class that defines a way for PayloadScoreQuery instances to transform the cumulative effects of payload scores for a document.
PayloadScoreQuery	A Query class that uses a PayloadFunction to modify the score of a wrapped SpanQuery NOTE: In order to take advantage of this with the default scoring implementation (ClassicSimilarity), you must override ClassicSimilarity.scorePayload(int, int, int, BytesRef), which returns 1 by default.
SpanPayloadCheckQuery	Only return those matches that have a specific payload at the given position.
