The log message indicates that the [search thread pool](https://www.elastic.co/guide/en/elasticsearch/reference/current/modules-threadpool.html) is at capacity of 1000, and so subsequent search requests are being rejected. Are you monitoring the cluster to understand the search load?

How many queries are you typically servicing concurrently? How many shards do these queries typically address? How many indices and shards do you have per node?
