57、索引管理_创建、修改以及删除索引

1、创建索引

创建索引的语法

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

示例

PUT /my_index
{
  "settings": {
    "number_of_shards": 1,
    "number_of_replicas": 0
  },
  "mappings": {
    "my_type":{
      "properties": {
        "my_field":{
          "type": "text"
        }
      }
    }
  }
}

2、修改索引

修改索引replica shard数量，primary shard不能修改

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
