Trying to create too many buckets. Must be less than or equal to: [65535] but was [65536]. This limit can be set by changing the [search.max_buckets] cluster level setting.

临时解决办法：

PUT /_cluster/settings
{"transient": {"search.max_buckets": 1000000}}

或者 

curl -X PUT "http://127.0.0.1:9200/_cluster/settings" -H 'Content-Type: application/json' -d '{"transient":{"search.max_buckets": 10000}}'

 --------------------------------------------------------------------------------------------------------------------------------

永久解决方法：

PUT /_cluster/settings
{"persistent": {"search.max_buckets": 1000000}}

 或者

curl -X PUT -k  "http://127.0.0.1:9200/_cluster/settings" -H 'Content-Type: application/json' -d '{"persistent":{"search.max_buckets": 1000000}}'
