You can configure our system to do this, or not to do this (and lots of other variations). I was just pointing out that to be generic for all Z39.50, I don't believe CQL should make more assumptions than Z39.50. Thus terms I think should be sent through to the server with all punctuation etc. The server then should normalize it (because it, and only it, knows the rules that the server uses). I don't think we are disagreeing with each other - I only wanted to make sure people we keeping the general problem in mind, not just a solution for a specific implementation. Alan
