I would rewrite it to this: cool gaming computer "cool gaming" "gaming computer" "cool gaming computer" Naively assuming a score of 1.0 for each hit, you would get something like... 1. "cool gaming laptop" => 3 (cool, gaming, "cool gaming") 2. "cool gaming lappy" => 3 (cool, gaming, "cool gaming") 3. "gaming laptop cool" => 2 (cool, gaming) And of course if it actually finds "cool gaming computer" it would get 6.
