关闭所有myidx-开头的索引的refresh（数据写入后没refresh就搜索不出来）

    1. #PUT myidx-*/_settings
    2. {
    3.     "index": {
    4.         "refresh_interval": "-1"
    5.     }
    6. }

    配置分片(shard)数，副本(replica)数，并配置作为写索引加入到别名(alias) myidx中

    1. #PUT myidx-write
    2. {
    3.   "settings" : {
    4.     "index" : {
    5.       "number_of_shards": 1,
    6.       "number_of_replicas": 0
    7.     }
    8.   },
    9.   "aliases": {
    10.     "myidx": {"is_write_index": true}
    11.   }
    12. }

    :::tips 注意number_of_shards只能在创建index的时候配置 :::
