I have a query with a nested boolean (boolean within a boolean) filter with a should clause that performs really terribly. But if I move the nested query up to top level, it performs as much as 50x faster. I am struggling to understand why this is the case. Here are the 2 forms:
https://gist.github.com/anonymous/cdbfbb940fa8da81019f You can see the "flattened" version simply repeats the query filter for each of the nested should clauses in the "nested" version. The initial "groups" terms filter is very selective. So I am thinking that the nested boolean filter query must somehow work on all documents rather than the ones filtered from that initial clause? Why would that be the case? -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
