It sounds like the behavior of FIS is different enough from topN that 'replace' is not in the cards. But it does sound like something that would be really nice to expose in Druid somehow. Maybe as a new query type? Can the 'weight' of an item be any Comparable object? (This would allow it to be compatible with any Druid aggregator.) Or is it limited to ints?
