Subject query performance with leading *
Date Mon, 13 Feb 2012 16:38:42 GMT
Hi,

Is there a way to improve query performance when using a leading * as a 
wildcard on a path property?

I have hundreds of queries to run on a lucene index (~250mo). Executing 
those queries without the leading * is about 5x faster than with the 
leading *. My problem is that I sometimes need to use the leading *.

Most of the queries have the full path as parameter but some of them 
have only a part of it.

The queries look like:
"+projet:CCOM +path:*/folder5/folder6/folder_ab/

I'm using lucene 3.1.0

Regards,
Gary
