I can't tell you the number of times that I've searched for Rust and get back results about protecting your old favorite car. And project names like corrode don't help narrow the search, it in fact raises the error rate.

It's funny, there was this company Yahoo! that was trying to organize the internet to try and fix this...

Another thing you can do is simply put a leading and trailing space in your search... " go " (quotes not needed)

If you use Ctrl+F for search, you can select "Whole Words" to "find go but not ago".

Ctrl-F has a 'Whole Words' option that should do what you want.

Edit: Oops, missed the same reply from xudongz

I've only had success searching HN for Golang.

searching for "r" is even worse.

Search for " go"?
