Hello, You could use a PhraseQuery with the terms "cool" and "gaming" and "computer" and set the slop factor you reckon is right. Then could assign a boost to this query only, which will make it bubble up the list. I don't think you can get away without specifying a slop factor though(like in the proximity scenario you mention).
