> This issue provides a new collector for situations where a client doesn't
> want more than N matches for any given key (e.g. no more than 5 products from
> any one retailer in a marketplace). In these circumstances a document that
> was previously thought of as competitive during collection has to be removed
> from the final PQ and replaced with another doc (eg a retailer who already
> has 5 matches in the PQ receives a 6th match which is better than his
> previous ones). This requires a new remove method on the existing
> PriorityQueue class.
