We are using the latest OSTicket v1.12 on Ubuntu 18.04 with mysql 5.7.26 and php 7.
There are no errors, but we just cannot search for a string in the message history. I don't get any ticket results when searching a string of text in tickets that isn't in the TicketThread/Last Response or TicketThread/Last Message.
Why can't we search anything in any of the thread? i.e. we have multiple tickets with a long thread referencing part numbers. When we search the part numbers, there are no tickets found in search.
