Trac recognizing duplicate bugs on bug submission

[Craig Harding]

Is there a way that an intermediate page could be introduced into trac
once the user has submitted a bug? It could show a list of existing
bugs that would match keywords from their bug submission. If there was
an existing bug that had a good match to the user's bug submission
they could skip that submission of the new bug and look at the
existing bug.

I tried searching the list for previous emails on this but I wasn't
really sure what this 'bug matching' would be called.

Craig.
