Description

Today the total hits threshold in the top docs collector is not inclusive, this means that total hits are tracked up to totalHitsThreshold-1. After discussing with @jpountz we agreed that this is not intuitive to return a lower bound that is equal to totalHitsThreshold even if the count is accurate.
