#创建 索引为blog 类型为article的文档

curl -H 'Content-Type:application/json' -XPUT http://localhost:9200/blog/article/1 -d '
{
      "id": "1",
      "title": "New version of Elasticsearch released!",
      "content": "Version 1.0 released today!",
      "priority": 10,
      "tags": ["announce", "elasticsearch", "release"]
}'

curl -H 'Content-Type:application/json' -XPOST http://localhost:9200/blog/article/ -d '
{
      "title": "Thress  version of Elasticsearch released!",
      "content": "Version 1.0 released today!",
      "priority": 10,
      "tags": ["announce", "elasticsearch", "release"]
}'

curl -H 'Content-Type:application/json' -XGET http://localhost:9200/blog/article/1?pretty

curl只想得到_source字段

curl -H 'Content-Type:application/json' -XGET http://localhost:9200/blog/article/1/_source

curl后加-i参数得到响应头

curl -H 'Content-Type:application/json' -i -XGET http://localhost:9200/blog/article/1?pretty

更新文档

curl -H 'Content-Type:application/json' -XPOST http://localhost:9200/blog/article/1/_update -d '{
  "script": "ctx._source.content = \"new content\""
}'

创建mapping

 curl -X PUT "localhost:9200/my_index"  -H  'Content-Type: application/json' -d '{
    "mappings": {
    		"my_maping": {
    			"properties": {
    				"title": {
    					"type": "text"
    				},
    				"content": {
    					"type": "text"
    				},
    				"priority": {
    					"type": "integer"
    				}
    			}
    		}
    	}
    }'

写入数据 tags对应的mapping会自动创建

curl -H 'Content-Type:application/json' -XPUT http://localhost:9200/my_index/my_maping/2 -d '
{
      "title": "New version of Elasticsearch released!",
      "content": "Version 1.0 released today!",
      "priority": 10,
      "tags": ["announce", "elasticsearch", "release"]
}'

增加mapping字段

curl -H 'Content-Type:application/json' -XPUT http://localhost:9200/my_index/_mapping/my_maping -d  '{
  "properties": {
    "attributeTags": {
      "type": "nested",
      "properties":{
           "name":{"type":"keyword"},
           "score":{"type":"double"}
        }
      }
    }
}'


attributeTags: {
small: 0,
vulgarCode: 1,
black: 1,
quality: 0.79
}

获取mapping

curl -XGET “http://localhost:9200/my_index/_mapping?pretty”

获取数据

curl -H ‘Content-Type:application/json’ -i -XGET http://localhost:9200/my_index/my_maping/1?pretty

#插入数据
curl -H ‘Content-Type:application/json’ -XPUT http://localhost:9200/my_index/my_maping/3 -d ’

{
      "title": "New version of Elasticsearch released!",
      "content": "Version 1.0 released today!",
      "priority": 10,
      "tags": ["announce", "elasticsearch", "release"],
      "attributeTags": {
       "small": 0,
       "vulgarCode": 1,
       "black": 1,
       "quality": 0.79
      }
}'

查询数据

curl -H 'Content-Type:application/json' -i -XGET http://localhost:9200/my_index/my_maping/3?pretty

curl -H 'Content-Type:application/json' -XPUT http://localhost:9200/my_index/my_maping/4 -d '

  {
        "title": "New version of Elasticsearch released!",
        "content": "Version 1.0 released today!",
        "priority": 10,
        "tags": ["announce", "elasticsearch", "release"],
        "testTags": {
         "small": 0,
         "vulgarCode": 1,
         "black": 1,
         "quality": 0.79
        }
  }'
