A bug arising from a UI snafu: if you enter a tag, and it is less popular than six other tags that it is a substring of, then it doesn't appear in the pop-up menu, and you can't add it to your tag set.

E.g., when I try entering [tex], the menu offers get "text", "latex" and four other tag names with "text" as a substring, but not "tex".

There might be a workaround for this, but I haven't figured it out. I propose changing the scoring mechanism so that exact matches are weighted highest.

We modified the tag-autocomplete logic so the exact match always shows up if it exists.

This is actually possible to accomplish in the current system. When you type out "tex", instead of hitting Enter or anything, just click off of the dropdown.

It'll give you the stats for the [tex] tag and let you add it properly. This is similar to the same scenario with tag preferences.

Even with the capability, though, I agree that exact matches should be provided in the dropdown. Here's a related proposal for this on all manner of tag dropdowns on the Q&A sites themselves: Please add exact tag matches to the autocomplete lists. I don't know if the mechanisms are identical, but doing both at the same time would be swell.

Yes, that works and the link to the [feature-request] is spot on. – Charles Stewart Nov 9 '10 at 20:01
