How Do I Set the search.max_buckets Parameter for an ES Cluster?

Function

If the query results on shards exceed the upper limit of records that can be returned (default value: 10000), you need to increase the limit by changing the value of search.max_buckets.

Solution

Run the following command on the Dev Tools page of Kibana:

PUT _cluster/settings
{
    "persistent": {
        "search.max_buckets": 20000
    }
}
