I'd like to do a search restricting the results to my own questions. I checked out the search tips and discovered this recommendation:

Advanced Super Ninja Search Options

posts from a specific user user:1234 apples oranges

So I tried...

user:Ethan vim  # I'm trying to find a question I asked about Vim a while ago.

There were many results, but none were questions of mine, at least not on the first page.

What's the correct way to do that?
