i'm thinking there should be another criteria for the sort as well, to find the results that have ALL of the result terms present, and the distance between the closest together set of them in the results... in many cases there will be results with the term multiple times so there will be clusters among them that are closer matches, even though the total distance of hits is wide

gonna ruminate over how to implement this extra metric, and add it to the sort so the results with more instances of search terms that have the full set of them get raised further up at the top of the results with more terms
