I literally wrote "search results will typically have all of the full title matches and fill up with about 60 partial matches"
I might have used other wording for the fill up, it is just an observation that you will often have around 60 matches. I guess those are the searches where there are few exact title matches and many partial ones. Try searching for tetris. Or try searching for something unpopular like chronometer and count the results.
But search is being overhauled right now. But if you really do search strategy, it will show you the tag strategy, where all games are to be found that have tagged strategy and are indexed.
