Why does the search fuction only return 3 threads?

[Moe]

For the past couple of days when I've been running a search by my user name to see where I've been lately, I only get 3 or 4 threads, obviously only the ones that have been posted to very recently.
Has the search function been limited?

That "since # of days" setting seems to have caught a lot of people off guard.
