Michael Busch commented on LUCENE-2111:
---------------------------------------
bq. Flex is generally faster.
Awesome work! What changes make those queries run faster with the default
codec? Mostly terms dict changes and automaton for fuzzy/wildcard?
How's the indexing performance?
bq. I think net/net we are good to land flex!
+1! Even if there are still small things to change/fix I think it makes sense
to merge with trunk now.

> Spinoff from LUCENE-1458.
> The flex branch is in fairly good shape -- all tests pass, initial search
> performance testing looks good, it survived several visits from the Unicode
> policeman ;)
> But it still has a number of nocommits, could use some more scrutiny
> especially on the "emulate old API on flex index" and vice/versa code paths,
> and still needs some more performance testing. I'll do these under this
> issue, and we should open separate issues for other self contained fixes.
> The end is in sight!
