关闭/打开索引
关闭：POST secisland/_close
打开：POST secisland/_open
关闭的索引只能显示索引的元数据信息，不能够进行读写操作。
可以同时打开或者关闭多个索引。如果指向不存在的索引则会抛出错误，可以使用配置ignore_unavailable=true，不显示异常。
全部索引可以用_all或者*打开或者关闭。因为关闭的索引会继续占用磁盘空间而不能使用，所以在一定程度上造成磁盘空间的浪费。
禁止使用关闭索引功能，
重建索引
POST _reindex
{
"source": {"index": "secisland"},
"dest": {"index": "secisland4"}
}
