五十八、Elasticsearch索引管理-创建、修改以及删除索引

1、创建索引语法

PUT /index
{
  "settings": {...},
  "mappings": {
    "type_one" : {...},
    "type_two" : {...}
    ...
  }
}

例如：

PUT /my_index
{
  "settings": {
    "number_of_shards": 2,
    "number_of_replicas": 0
  },
  "mappings": {
    "my_type" : {
      "properties": {
        "my_field" : {
          "type": "text"
        }
      }
    }
  }
}

2、修改索引

将shard副本从0变成1

PUT /my_index/_settings
{
  "number_of_replicas": 1
}

3、删除索引

DELETE /my_index
DELETE /index_one,index_two
DELETE /index_*
DELETE /_all
