I'm attempting to optimize a query using the Search Profiler in Kibana. I'm having issues as it appears ES keeps caching something so my first query is slow and subsequent ones are quick.
I have attempted the following on the index but it does not appear to help: 'POST /index-name/\_cache/clear'
Is there another step I need?

Hey,
so that is clearing the caches used within the heap of the Elasticsearch JVM. However there are other caches like the Linux Kernel Page Cache, which are not cleared - that cache is responsible to keep that is frequently accessed in the main memory.

I also tried the following, closed the index, and modified the following setting:
```auto
PUT /index-name/_settings
{
"index.queries.cache.enabled" : "false"
}
```
After opening the index I think the queries are still being cached.

What makes you think so? Have you checked the index stats?
