Subject [jira] Resolved: (LUCENE-1178) Hits does not use MultiSearcher's createWeight
Date Wed, 11 Jun 2008 06:12:45 GMT

Otis Gospodnetic resolved LUCENE-1178.
--------------------------------------

    Resolution: Won't Fix

With Hits getting deprecated, I think it doesn't make sense to pursue this.  If anyone disagrees,
we can reopen.

> I am developing a distributed index, using MultiSearcher and RemoteSearcher. When investigating
some performance issues, I noticed that there is a lot of back-and-forth traffic between the
servers during the weight calculation.
> Although MultiSearcher has a method called createWeight that minimizes the calls to the
sub-searchers, this method never actually gets called when I call search(query).
> From what I can tell, this is fixable by changing in Hits.java the line:
> weight = q.weight(s);
> to:
> weight = s.createWeight(q);
