Robert Muir updated LUCENE-2694:
--------------------------------
Attachment: LUCENE-2694_hack.patch
here's a hack patch (dont think it actually works) just showing what i mean.
I think termsenum should only have seek(TermState).
in the hack-patch, i made the termState() and seekTermState() non-abstract:
the default impl returns a 'SimpleTermState' containing the term bytes and
saved docFreq and implements seek(TermState) with those bytes.
This is basically what the patch had everywhere anyway as an implementation
(for many of these, we should use more efficient impls, i fixed this for
MemoryIndex as an example, but MultiTermsEnum comes to mind).
Also, i don't understand what was going on with setting bytes on the
DeltaBytesReader with your seek(BytesRef, TermState) before.
If StandardCodec needs to know the shared byte[] prefix or something like that
to reposition the enum, then it
should put this in its termstate.
> MTQ rewrite + weight/scorer init should be single pass
