Yeah, this help page is fairly easy to find (two clicks: ? icon -> "How to search"). I figured I'd ask because for example `max` is not documented there, even though it's pretty important for the sort of stuff I use Sourcegraph for (i.e. finding out all the repos that use X).
(We will improve our docs here & make them stand out more in the app regardless, I think that is a great suggestion.)
I also very much want multi-line searches, I can't wait for them :)
