Problems with searches that include user number

As of today, I've been having some weird behavior in searches that include the user number.

If I click on a tag in my user page, so that it performs a search for that particular tag and my user number, I'm getting no hits; for example, searching for [group-theory] user:742 is returning no matches, even though I've posted over 50 answers in such questions.

Update: I can confirm Rahu Narain's observation that if perform the search on a tag in which I've asked a question, then the question is displayed.

Searching for just the tag seems to produce no problems. Searching only for user:742 does find some hits, but the page result looks weird. I've tried a few users (not just me), they are all giving me trouble. The problem also seems to be occurring in Meta, with searches for user-and-tag returning no matches even when some should exist.

Update 2: I've reported this at the main site; I'm told there will be a temporary fix for the user-page links as well as one for the display problem when searching for a user in the next build.

Final Update: The searches seem to be working now. Could a moderator mark this as resolved?

• I'm seeing the same behaviour. It looks like it no longer returns questions one has answered for that tag, but only questions one has asked. This is inconsistent with the number displayed next to the tag, and the previous behaviour was much more useful, so I hope the SE admins consider this a bug and not by design. – Rahul Jan 28 '11 at 3:01
• @Rahul: Thanks; how about a search for just your user number? Are you getting regular behavior, or weird display? – Arturo Magidin Jan 28 '11 at 3:59
• Yes, that page's layout is definitely broken. – Rahul Jan 28 '11 at 4:18
