Can we get a proper search, rather than the half-hearted one there is now.

example:
I know a worked on "mimecast archive" for a certain user a while back

When I try
"mimecast archive" "melanie" not even the current ticket comes up

mimecast And Melanie , finds Andrews...

I know I can list the user closed tickets, but the format of a web page, and having to load each scroll down means I can't even ctrl-f and search it like that.

Basically search as it is, is worthless for finding previous tickets.
Please put in a decent search
