Sorry, can't give you any Compass info but from posts to this list it appears to be fairly well used. And there is a good argument that you shouldn't worry about performance in advance. > In my application, I have two entities e.g Article and Group.

Just do as you say: store the group ids with each article e.g. id: article1 text: some text about something groupid: 100 200 300 id: article2 text: some other text about something else groupid: 400 Then you can add a groupid: nnn clause to your query. As ever, you'll need to make sure that you use a suitable analyzer at indexing and search time. -- Ian. --------------------------------------------------------------------- To unsubscribe, e-mail: java-user-unsubscr...@lucene.apache.org For additional commands, e-mail: java-user-h...@lucene.apache.org
