Elasticsearch-6.x.x 索引管理

1.创建索引

PUT exchange

{
  "acknowledged": true,
  "shards_acknowledged": true,
  "index": "test"
}

注意：索引名不能包含大些字母

2.指定参数创建索引

PUT blog
{
  "settings": {
    "number_of_shards": 3,
    "number_of_replicas": 1
  } 
}

{
  "acknowledged": true,
  "shards_acknowledged": true,
  "index": "blog"
}

3.查看索引

3.1 查看指定索引的配置信息

GET blog/_settings

{
  "blog": {
    "settings": {
      "index": {
        "creation_date": "1515458969949",
        "number_of_shards": "3",
        "number_of_replicas": "1",
        "uuid": "A7pKNO7bTgucu1uNgmXlQg",
        "version": {
          "created": "5060399"
        },
        "provided_name": "blog"
      }
    }
  }
}

4.删除索引

DELETE test

{
  "acknowledged": true
}

5.添加索引并指定类型字段信息

PUT exchangehistory
{
    "settings" : {
        "number_of_shards" : 5
    },
    "mappings" : {
        "record" : {
            "properties" : {
        "amount": {
          "type": "float"
        },
        "contract": {
          "type": "text",
          "fields": {
            "keyword": {

              "ignore_above": 256
            }
          }
        },
        "exchange_time": {
