Subject Re: perf enhancement and lucene-1345
Date Mon, 04 May 2009 23:10:22 GMT
Michael:
   Actually this is not what I meant.

   It was discussion that was wrapped in  Lucene-1345 where I posted some
optimizations for Conjunction and Disjunction Scorers and some numbers.
Because of the confusion of what  Lucene-1345 is, the loop was never closed.
I am just writing to follow up.

Thanks

-John
