Michael McCandless updated LUCENE-4230:
---------------------------------------
Attachment: LUCENE-4230.patch
Initial patch, just with a rote cutover of the current boolean
needsOffsets to bit wise flags instead; next I'll at a flag for
payloads and (carefully) fix all places that pull D&PEnum to state
whether they need payloads...
> When pulling DocsAndPositionsEnum you should state whether you need payloads

> Payloads are extra-costly today because when pulling a
> DocsAndPositionsEnum, the codec has no way to know if you need access
> to the payloads. Tracking the payloads, even if the app never
> retrieves them, is often costly...
