)

)
We currently always compute the total hit count when searching, but we could avoid that in
some cases, for example when the user asks only for the hits.
Elasticsearch 7 provides the {{track_total_hits}} parameter to control that, and in Lucene
we could remove the TotalHitCountCollector.
We should also look how to take advantage of the related optimization in Lucene allowing
to stop the search when it's certain it cannot find any more hits. I don't recall
the name of See this optimization, but video for more info on how it was mentioned in a
presentation in the Search devroom at Fosdem 2019, in the afternoon works:
