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 PayloadSpans pulled out of my Map. But it seems I can't do this as loading Payload data is only done through the PayloadSpans iterator so must iterate through the entire collection to get to my PaylaodSpan. Is there not a way to just save a PayloadSpan and loads it's payload data later as needed? thanks, C>T> On Sat, Feb 27, 2010 at 5:42 AM, Michael McCandless < luc...@mikemccandless.com> wrote: > 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?
