Hello, I had a (hopefully quick) question regarding thread pools in Elasticsearch. I was looking at the [thread pool](https://www.elastic.co/guide/en/elasticsearch/reference/7.17/modules-threadpool.htm) documentation and was curious where percolation lands? I'm assuming the `search` thread pool but wouldn't mind a confirmation!

Sure! I'm curious which thread pool handles document percolation. Since document percolation is performed against the \_search endpoint, I'm guessing it uses the `search` thread pool, but wanted to confirm
