Hi everyone, I have one query _search with four separated nested terms aggregation and filters in the aggregations, this query is retrieving data in about 2 seconds when a specific term is searched. I splitted the four queries into four different requests in a _msearch, each one with an aggregatio…

Each query executes in a single thread against each shard, although querying of multiple shards is done in parallel. If you send 4 separate aggregation in parallel over in an _msearch query they run in parallel across all shards.

Does aggregations runs in parallel?

_search aggregates run sequentially. _msearch they do run in parallel and you can control how many can in concurrently using max_concurrent_searches
