The duplicate tagging idea

[Sitsofe Wheeler]

The other day I was discussing duplicate bugs in launchpad with a friend
at lunch and outlined a rough idea of a system to try and cut back on
dupes (while collecting a few stats too).

The idea is that when you go to file a new bug you are given the option
to put in 3 or more tags to search for your bug in launchpad. If the
tags are found in other bugs then they are shown as likely candidates
and the user is given the option to view them.

If the user goes on to file a report those search tags are also saved
with the report and the bug as a tag summary to aid in its discovery.

If a bug report is duplicated against another, a note is made and when
searches are done its tags are "added" to the original report's tags to
make the original more likely to be found.

The option to bypass the tag search is offered but is recorded into a
bug report. This way at a later stage it can be determined whether
tagging is an effective system by checking how many bugs which never had
a search done ended up actually being dupes versus bugs that did have
tag search done.

What do people think?
