hello,

Can anyone please advice how to improve a query performance?

- the bool filter takes 50ms.

- filter dates: last 7 days

- total search documents : 20075

- total index documents : 79m

- searched indices: 1

- index primary shard size: 9.2gb

- primary shards: 2

- replica:1

- storage tier: hot

thank you!

Usually I'm used to much better performance.  
I'm trying to keep 2 seconds as target number

If your index is only 9.2GB in size, why have 2 primary shards? What is the hardware specification of the cluster? What is the full output of the [cluster stats API](https://www.elastic.co/guide/en/elasticsearch/reference/7.13/cluster-stats.html)?

I can decrease the shards via ilm, and do rollover..  
attached below, thanks!

@Christian_Dahlqvist @warkolm any tips you can think of? Is 90 million too many documents per index?
