Finding existing tickets before opening new ones on trac

We're using Trac as the task management tool at the project we work in. However, Trac search is maybe not the most intuitive search out there, and we end up having multiple duplicates as the reporters can't effectively find if there already is a reported ticket of the question he or she found.

Stack Overflow's "Related Questions" concept is g开发者_如何学Goreat and works magnificently! I was wondering if someone has heard of some similar plugin to Trac, or if you have solved this problem some other way.

For trac stuff always turn to trac-hacks

Here is one it looks right for you, DuplicateTicketSearchPlugin: Provides an AJAX-style lookup for duplicate tickets, used on the New Ticket page. Automatically searches for related tickets based on the summary field.
