Subject [jira] Updated: (LUCENE-2041) Complete parallelizaton of ParallelMultiSearcher
Date Tue, 10 Nov 2009 15:57:27 GMT


Simon Willnauer updated LUCENE-2041:

    Attachment: LUCENE-2041.patch

Added some more final keywords and generalized HitQueue to PriorityQueue<ScoreDoc> 
in search (no sort)

I guess we are set with this patch, good team work Uwe! Lets get this out for heavy committing!

I get the impression that we should think about moving stuff like the Function interface out
to utils. This could be useful in many situations though. Thoughts?

> ParallelMultiSearcher is parallel only for the method signatures of 'search'.
> Part of a query process calls the method docFreq(). There was a TODO comment to parallelize
this. Parallelizing this method actually increases the performance of a query on multiple
indexes, especially remotely.
