If you know the structure of the index ahead of time and the weights you
want to place on the different levels I'd do a query expansion. i.e.
search2:coco
would become
search2:coco^4 OR search4:coco
but actually creating the query objects rather than generating the
string to be parsed by the QueryParser.
