ES命令

• 创建索引

PUT /indexName
{
  "settings": {
    "number_of_shards": 5,
    "number_of_replicas": 1
  }
}

同时创建mapping

PUT /indexName
{
  "settings": {
    "number_of_shards": 5,
    "number_of_replicas": 1
  }，
  "mappings": {
    "properties": {
      "id":{
        "type":"integer"
      },
      "title":{
        "type":"keyword"
      }
    }
  }
}

number_of_shards 分片数
number_of_replicas 副本数

• 修改索引

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

可以改number_of_replicas，不能改number_of_shards

• 删除索引

DELETE /indexName

{
  "properties": {
     "name": {
        "type": "text"
     },
     "description": {
        "type": "text"
     }
  }
}
