Subject Re: exclusions by query and many values
Date Thu, 09 Aug 2012 19:49:27 GMT
Thanks for the response, Jack...but as I mentioned, we are currently doing
pretty much what you suggest.  When customers login, we pull their list of
exceptions and create the filter query to use on all queries within their
session.

This works good, but as I also mentioned, its getting hard to manage and
the query is awfully long. I'm expecting it to start hurting performance,
so I was hoping there may be another technique or method to do this aside
from filter queries.
