Yonik, Thanks for the input. We'll try this out. And you're right - I tried to simplify our first operation's description.

If you want to avoid double-caching of norms, then you should call getDocIdSet() for each segment reader, not the top level reader. Aside: presumably you're actually doing something more advanced than getting the hit count (and you just simplified your description because it wasn't pertinent)... since you can get the hit count from TopDocs. -Yonik http://www.lucidimagination.com --------------------------------------------------------------------- To unsubscribe, e-mail: java-user-unsubscr...@lucene.apache.org For additional commands, e-mail: java-user-h...@lucene.apache.org --------------------------------------------------------------------- To unsubscribe, e-mail: java-user-unsubscr...@lucene.apache.org For additional commands, e-mail: java-user-h...@lucene.apache.org
