Subject [jira] Commented: (LUCENE-1345) Allow Filter as clause to BooleanQuery
Date Mon, 20 Apr 2009 22:06:47 GMT


Paul Elschot commented on LUCENE-1345:

The interesting thing to benchmark is filtered queries. One could do this by adding the filter
as a required clause to a BooleanQuery in IndexSearcher, and see whether filtered queries
are faster with that implementation. This part should work normally with the current patch.

In case that turns out to make a real difference, it might also be considered to deprecate
all the Searcher methods that take a Filter argument, and indicate the preferred alternative
implementation with a Filter as a clause to BooleanQuery in the javadocs.

Now, if I could find the time to get this last bug out of the current patch...
