Han Jiang updated LUCENE-3069:
------------------------------
Attachment: LUCENE-3069.patch
Patch, revive IntersectTermsEnum in TempFSTOrd.
Mike, since we already have an intersect() impl, maybe we can still keep this?
By the way, it is easy to migrate from TempFST to TempFSTOrd.
> Lucene should have an entirely memory resident term dictionary

> FST based TermDictionary has been a great improvement yet it still uses a
> delta codec file for scanning to terms. Some environments have enough memory
> available to keep the entire FST based term dict in memory. We should add a
> TermDictionary implementation that encodes all needed information for each
> term into the FST (custom fst.Output) and builds a FST from the entire term
> not just the delta.
