Simon Willnauer updated LUCENE-2694:
------------------------------------
Attachment: LUCENE-2694.patch
here is a new patch with a slightly different implementation of
PerReaderTermState. I build a view from the subreader used to build the MTQ
which is shared across all PerReaderTermState instance for the query. The PrTS
then uses only the ordinal from the ReaderView to reference a TermState which
prevents us from creating Map instances for each term. In turn this also made
it possible to fall back to re-seeking the TermDict if the reader is not in the
view.
I fixed all other issues and all tests including the highlighter pass now.
> MTQ rewrite + weight/scorer init should be single pass
