Elasticsearch|Elasticsearch 7 : 创建和删除索引 Elasticsearch7:创建和删除索引

创建索引假设索引名是 movie ：

PUT http://127.0.0.1:9200/movie?pretty

【Elasticsearch|Elasticsearch 7 : 创建和删除索引】返回

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

设置索引数据结构指定 mapping 和 settings

PUT movie { "mappings" : { "properties" : { "name" : { "type" : "keyword" } } }, "settings" : { "index" : { "number_of_shards" : 1, "number_of_replicas" : 2 } } }

查看索引信息

GET movie

{ "movie" : { "aliases" : { }, "mappings" : { }, "settings" : { "index" : { "creation_date" : "1572843447230", "number_of_shards" : "1", "number_of_replicas" : "1", "uuid" : "AzEtRiBaQqO5JDN_l7WG-w", "version" : { "created" : "7020099" }, "provided_name" : "movie" } } } }

创建文档时自动创建索引当向一个不存在的索引中写入文档时，会自动创建索引。（注意不需要的话，要关闭此功能）
