Michael McCandless commented on LUCENE-2694:
--------------------------------------------
The failure in TestFSTs is because PrefixCodedTermsReader is somehow returning
an OrdTermState when its terms index (var gap) does not support ord.
The ord member of PrefixCodedTermState is undefined when the terms dict doesn't
support ord (ie when ord() throws UOE).
So to fix this we should fix TestFSTs to go back to calling .ord() and catching
the UOE, maybe? Separately, make sure you don't overwrite storeOrds in that
test. Ie the test randomly sets it to true or false (so that we test both
cases); only if the terms index cannot suppord ord should we wire it to false.
If it can support ord then we should leave it as the random value...
> MTQ rewrite + weight/scorer init should be single pass

> Once we fix MTQ rewrite to be per-segment, we should take it further and make
> weight/scorer init also run in the same single pass as rewrite.
