Thanks for your response Nick! I was referring to the "app\_search.engine.total\_fields.limit" setting, let me see if I can break it down: Scenario 1: 100 fields (stored but not searched) 10 fields searched and used for relevance tuning 5 fields returned Scenario 2: 800 fields (stored but not searched) 10 fields searched and used for relevance tuning 5 fields returned I think the performance be about the same since I'm searching over the same amount of fields? > [@64 fields limitation in 7.16.3](https://discuss.elastic.co/t/64-fields-limitation-in-7-16-3/304322): > > Hello, How can we increase the Schema Fields limit in 7.16.3 release?
