If you want to increase the maximum search thread pool queue size from the default 1000 to for instance 2000, just add the following to your **elasticsearch.yml** file

`thread_pool.search.max_queue_size: 2000`

and then restart the node for the setting to take effect. Repeat on the other nodes in the cluster.
