> When running a search concurrently, collectors which have collected the number of hits requested locally i.e. their local priority queue is full can then globally publish their bottom hit's score, and other collectors can then use that score as the filter. If multiple collectors have full priority queues, the maximum of all bottom scores will be considered as the global bottom score.
