I guess the word "smartos" is not found, then the typo correction results are shown instead. I like the hnsearch.com too, but that will be shutdown soon. The interesting thing to me is they are using ThiftyDB which is a full-text database providing fast performance instead of the file-based search. I think the files have the indexes, but they are not scale if not using some kind of database on the backend. Somehow the fast response to the key strike is not that preferred. Google provides autocomplete for the keywords when we are typing. hnsearch.com just let user to finish want they want to search. They are ok to me.
