I didn't even see this in the feature list before doing the signup. One of the signup questions is "how do you usually search?" or so, I wrote in the blank "I want to search for symbols, not substrings, so if I'm searching for `bar` I don't want `foo_bar` to show up as a match". I usually do this with word boundaries in regexes, but I pretty much have to have the repo downloaded, so it's useless for searching on github.com this way.
