When I paste a hash into the search box on https://chromiumdash.appspot.com/commits, I get an error message:
"Error: Invalid query format. Valid format includes any combination of user:<email-id> commit:<git hash> repo:<repository name>"

Could we allow searching for commits without using a strict syntax? That would simplify looking up commits a lot :)

It would also be great to do syntax-free search for authors. Maybe search could try to do substring matching on <hash>, <revision> and <author> if no parameter is given?
