When I include the date in an advanced search on the Zimbra web client, I get an error "unable to parse the search query". This happens on ZCS 4.5.1 and 4.5.3. I'm running Firefox 1.5 on Linux.
It happens whether I select "on", "before" or "after", whichever date I choose and if date is the only criterion for the search or one of several.
Is this a bug, or am I doing something wrong?
