Performance comparison: KQL vs ES|QL vs DSL

Hi!

I'm facing some performance degradation with my ELK setup. I believe that poorly written querys are one of the main causes of this degradation. Due to the specific use cases I must write queries with a lot of OR statements. I understand that it's suboptimal. But, can the query performance be improved by switching to a different query language. Also how can I optimize the queries with 10-15 OR statements?
