0 _search查询数据时可以指定多个index和type
GET /index1,index2/type1,type2/_search GET /_all/type1/_search 相当于查询全部index下的type1的document GET /_all/type1/_search?from=0&size=5 from和size为分页参数
1 增加一条数据，手动指定document的ID
PUT /index1/type1/1 { "content1":"abcnt地方士大夫", "age":"abc你的" }
2 增加一条数据，自动指定document的ID
POST /index1/type1 { "content1":"abcnt地方士大夫", "age":"abc你的" }
3 获取一条数据的方式，并指定查询返回字段
GET /index1/type1/1?_source=age,content1
4 es更新数据时使用自定义版本号，只有版本号大于当前版本号才允许更新操作
PUT /index1/type1/1?version=5&version_type=external （之前的_version属性必须小于5） { "description":"程序员一枚~~~" }
5 partial update对document中的部分field进行更新
POST /index1/type1/1/_update?version=13 （必须version等于当前版本号时才可以修改数据，而且内容和原来相同则认为未更改版本号不变；该操作在更新期间不会被打断） { "doc":{ "description":"程序员一枚~~~7778899056" } }
6 通过GET /_mget 批量查找数据，需要提供index，type，id（可以通过url参数增加，根据搜索范围不同使用不同的查询参数）
GET /_mget { "docs":[ { "_index":"index1", "_type":"type1", "_id":"1", "_version":16 }, { "_index":"index1", "_type":"type1", "_id":"2" } ] } GET /index1/_mget { "docs":[ { "_type":"type1", "_id":"1", "_version":16 }, { "_type":"type1", "_id":"2" } ] } GET /index1/type1/_mget { "ids":[1,2] }
7 _search搜索默认查询前10条（timeout=1ms可以指定超时时间）
GET /index1/type1/_search?timeout=1ms
8 使用_search?q=xxx，为全字段查询，如果使用_search?q=field:xxx为按照具体字段进行查询；
PUT /index3/type3/1 { "date":"2019-01-02", "name":"the little", "content":"Half the ideas in his talk were plagiarized from an article I wrote last month." } PUT /index3/type3/2 { "date":"2019-01-01", "name":"a dog", "content":"is the girl, women's attention and love day. July 7th Qiqiao customs, originated in the Han " } PUT /index3/type3/3 { "date":"2019-07-01", "name":"very tag", "content":"Some of our comrades love to write long articles with no substance, very much like the foot bindings of a slattern, long as well as smelly" } //但是按照具体字段查询时如果字段类型为date或者long等时间和数值类型则使用exact value去匹配 GET /index3/type3/_search?q=date:2019-01 //只能查询出1条数据，查询方式为exact value GET /index3/type3/_search?q=2019-01 //则能查询出3条，因为会使用full text全字匹配，会将每一可能的部分都进行分词，只要包含则可以查询出来
9 使用mapping指定索引字段的类型以及是否要进行分词，但是手动创建索引的mapping，只能给新字段指定，或者还没创建的索引指定，mapping不能修改
DELETE /index3 //创建索引并指定字段的属性 PUT /index3 { "mappings": { "type3": { "properties": { "date":{ "type": "date"//日期类型的exact value匹配粗略除外，es会按照搜索的部分日期匹配出一个返回.如：GET /index3/type3/_search?q=date:2019 }, "name":{ "type": "keyword" }, "no":{ "type": "long" }, "content":{ "analyzer": "standard", "type": "string" } } } } } //添加数据 PUT /index3/type3/1 { "date":"2019-01-02", "name":"the little", "content":"Half the ideas in his talk were plagiarized from an article I wrote last month.", "no":"123" } PUT /index3/type3/2 { "date":"2019-01-01", "name":"a dog", "content":"is the girl, women's attention and love day. July 7th Qiqiao customs, originated in the Han ", "no":"6867858" } PUT /index3/type3/3 { "date":"2019-07-01", "name":"very tag", "content":"Some of our comrades love to write long articles with no substance, very much like the foot bindings of a slattern, long as well as smelly", "no":"123" } GET /index3/type3/_search?q=name:very tag 使用字段名称只能exact value策略匹配可以查询的到，因为type指定为keyword
