I know that you can limit searches to just your own posts by typing:
in the Search box, e,g, "user:1322 fpga" (since I am usernumber 1322) to search all my own posts (questions and answers) that include fpga in them.
But what's with this usernumber business? Why can't I just type in a username like this?
Doesn't seem to be much of a stretch to convert the latter into the former.
