That's right, for unknown keywords, the entire search string (including keyword part) is interpreted as search query. But I'm not sure if showing no results is the right thing to do. Keywords were meant for power users, majority of people won't even know they exist, so making ":" return nothing for them (if they happen to put it in the query) will be confusing.
