Hoss means calling rewrite on the *result* of a rewrite. So the application would call rewrite, cache the resulting query, and then use that already rewritten query from then on. Lucene wouldn't know it had already been rewritten, and would call rewrite again, but it should be fast. -Yonik --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
