ElasticSearch(ES)索引库与文档的创建和操作

索引库操作有哪些？

• 创建索引库：PUT /索引库名
• 查询索引库：GET /索引库名
• 删除索引库：DELETE /索引库名
• 添加字段：PUT /索引库名/_mapping

##创建索引库
PUT /test
{
  "mappings": {
    "properties": {
      "info": {
        "type": "text",
        "analyzer": "ik_smart"
      },
      "email": {
        "type": "keyword",

            "type":"keyword"
          }
        }
      }
    }
  }
}
#查询索引库
GET /test/_mapping

GET /test/_search

#修改（新增）索引库字段
PUT /test/_mapping
{
  "properties":{
    "age":{
      "type":"integer"
    },

• 创建文档：POST /{索引库名}/_doc/文档id { json文档 }
• 查询文档：GET /{索引库名}/_doc/文档id
• 删除文档：DELETE /{索引库名}/_doc/文档id

• 修改文档：

  • 全量修改：PUT /{索引库名}/_doc/文档id { json文档 }
  • 增量修改：POST /{索引库名}/_update/文档id { "doc": {字段}}
