wilcards in searches
Short, concise description of the idea
It's currently very difficult to find someone if you "sort of know" what their username is, and you can't look for people whose usernames contain a certain string but aren't just that string. Being able to use wildcards in searches would help this.
Full description of the idea
I don't know if it's possible to set up the LJ search so that it can use wildcards, but it would be nice if you were looking for people with a certain string in their usernames, or email, or something, like all users who had "speth" or "english" or "xy" or something. I've seen searches do this (usually without being asked explicitly) and think it would be neat. I thought of it when looking for lj_english, because I didn't know what it was called, but I knew it had to have "english" in it.
