Conversation
In certain situations we can early terminate and just skip the entire query phase or make the lucene level rewrite very cheap if we can already tell that a query won't match any documents. For instance if there is a single `match_none` ie. due to some range rewrite in a filter or must clause of a boolean query it can just drop all it's other queries since it will never match.
