It's not implemented, but http://issues.apache.org/jira/browse/LUCENE-1888 is
how I would solve it. It probably isn't that hard to implement, actually. A
patch would be great. Happy to review one.

What I'd ideally like to do is to take SpanQuery, loop over the PayloadSpans
returned from SpanQuery.getPayloadSpans() and store all PayloadSpans for a
given document in a Map by their doc id.
Then later after deciding in memory which documents I need, load the Payload
data for just those PayloadS

If it matters it doesn't need to be sequential. I just need access to all the
payloads for a given
You can also access payloads through the TermPositions enum, but, this
is by term and then by doc.
It sounds like you need to iterate through all terms sequentially in a
given field in the doc, accessing offset & payload? In which case
reanalyzing at search time may be the best way to go.

Thanks for the information. S
Hello,
To my knoweldge, the character position of the tokens is not preserved by
Lucene - only the ordinal postion of token's within a document / field is
preserved. Thus you need to store this character offset information
separately, say, as Payload data.
