i found the basic search in new version is not support to search some kind key, such as a ip address (x.x.x.x) ,non-English words, but it is working well in old version
In old version I could search by word for field "SUBJECT" ... now I can't.I can search only by email or ID number of ticket.
I have the same problem and seem to have an accompanying error in my PHP logmaybe the same or similar issue for you?http://forum.osticket.com/d/discussion//search-broken-after-upgrade-from-1-9-3-to-1-9-4#latestAlso a bug report linked there.
