Bug Description

Environment: 1.4

User can filter pages by their tags but it's case sensitive. It depends how user enters tag on the Edit Title and Description page (using lower or upper case).

importance: Undecided → Medium
status: New → Triaged
tags: added: tags

I think that we should probably fix it (a status of "opinion" means "wontfix"), but I'm not entirely sure how yet.

Perhaps a good first step would be to lowercase all new tags entered by users.

In postgres it wouldn't be a big problem to leave the contents of the db alone, we could just add an index on LOWER(tag) and lowercase the search terms. But for mysql the easiest way would be to do what Hugh did in that patch - basically destroy data by lowercasing everything in the tag column (removing dupes first to avoid the pk error). Anther option would be creating a new indexed column and putting the lowercased tags in there.
