Your second example for ‘gox’ is what I’d expect if there are no results for any reason.
Otherwise it just looks like “nothing happened what’s going on?” - how about some user feedback so the user knows what’s going on? Putting in “go” and getting no response from the interactive box is pretty confusing. The second example is much, much less confusing.
For the “go” search why not tell the user, “you’ll need at least 3 characters to search” instead remaining dormant?
