Payloads are added during analysis onto the Token. Have a look in the
contrib/analyzers module in 2.3 or the trunk version of Lucene. There
are a couple of examples in there that add payloads to tokens (see the
payloads package at
http://lucene.apache.org/java/2_3_0/api/contrib-analyzers/org/apache/lucene/analysis/payloads/package-summary.html)
. You can use the BoostingTermQuery to use the payload as a factor
in scoring, or, you might be able to write your own custom Sort, but I
haven't thought that all the way through just yet.
Michael B. also has an excellent talk from last year's ApacheCon that
covers payloads at http://people.apache.org/~buschmi/apachecon/AdvancedIndexingLuceneAtlanta07.ppt

Hi All,
I want to store information in Payload. How do I write Payload value
to Index. How to I sort value depending upon the Payload?
I could not find any method in Document class which takes Payload as
argument.
