Hopefully this isn't a duplicate, but I did try to find it. Searching for documentation as a developer can be frustrating sometimes in Firefox, since common identifiers like "array.prototype.splice" get interpreted as "http://array.prototype.splice/". We should research ways of addressing this. Chromium does not exhibit the same behavior: if you search for "array.prototype.splice" it correctly interprets it as a search. It will however present you with a little "Did you mean http://array.prototype.slice?" window. From what I can tell, Chromium just uses the top-level domain to guess whether you're searching or not (array.prototype.slice.com will be interpreted as http://array.prototype.slice.com/). This seems like pretty reasonable behavior.

I'm sorry, it's a dupe. As a temporary workaround for now, we have added a second entry that does a search, just after the first entry that tries to visit the url.
