添加具体的文档

插入文档自动生成id	Post	http://localhost:9200/testindex/testtype/ post每次都是创建新的	{     "name":"张明",     "address":"中山北路" }
插入文档，更新或生成	put	http://localhost:9200/testindex/testtype/1 put时带具体的ID，表示修改，没有则创建	{     "name":"张明",     "address":"中山北路" }

其他操作：

插入文档自动生成index/type	Post	http://localhost:9200/testindex/testtype/ post每次都是创建新的	{     "name":"张明",     "address":"中山北路" }
插入文档自动生成index/type	put	http://localhost:9200/testindex/testtype/1 put时带具体的ID，表示修改，没有则创建	{     "name":"张明",     "address":"中山北路" }
同时创建index、type，不插入文档	Post/ put	http://localhost:9200/testindex   后面的json格式最好不要变动，一般情况下，只要post过去的内容和查询看到的格式保持一个层次结构，都可以提交； 但是提交的格式却不一定和查询看到的一致（毕竟提交只是需要将所有的信息加上去就可以了）	{       "settings" : {         "number_of_shards" :   "5",         "number_of_replicas" :   "1"     }      ,         "mappings" : {       "testtype" : {         "properties" : {           "address" : {             "type" :   "string"           },           "age" : {             "type" :   "string"           }         }       }       }     }
刷新索引	Post	http://localhost:9200/testindex/_refresh
提交索引	Post	http://localhost:9200/testindex/_flush
优化索引	Post	http://localhost:9200/testindex/_optimize
清空缓存	Post	http://localhost:9200/testindex/_cache/clear

 

 

查询操作：

Math_all 全集查询	Post	http://172.16.20.49:9200/zuhe/zuheentity/_search http://172.16.20.49:9200/*/zuheentity/_search http://172.16.20.49:9200/*/_search http://172.16.20.49:9200/_search	{  }
Math 语义查询	Post	http://172.16.20.49:9200/zuhe/zuheentity/_search http://172.16.20.49:9200/*/zuheentity/_search http://172.16.20.49:9200/*/_search http://172.16.20.49:9200/_search	{     "query":{         "match":{                        "ManagerName":"财富"         }     } }
Math_phrase 短语查询，term查询后，进行位置匹配，得到类似like结果	Post	http://172.16.20.49:9200/zuhe/zuheentity/_search http://172.16.20.49:9200/*/zuheentity/_search http://172.16.20.49:9200/*/_search http://172.16.20.49:9200/_search	{     "query":{         "match":{                        "ManagerName":"财富"         }     } }
Term 直接用倒排索引的词项进行查询，性能好，但在应用层面，直接使用的少	Post	http://172.16.20.49:9200/zuhe/zuheentity/_search	{     "query":{         "term":{                        "ManagerName":{                 "value":"财",                 "boost":10             }         }     } }
Wildcard 在term查询的基础上，增加通配符功能	Post	http://172.16.20.49:9200/zuhe/zuheentity/_search	{     "query":{         "wildcard":{                        "ManagerName":{                   "value":"?*"                ,                 "boost":10             }         }     } }
Terms 最低匹配查询已不再支持，需要使用bool查询	Post	http://172.16.20.49:9200/zuhe/zuheentity/_search	{     "query":{         "terms":{                        "ManagerName":["富","宇","财","富"]              ,"minimum_match": 1         }     } }
query_string +-前面注意要有一个空格	Post	http://172.16.20.49:9200/zuhe/zuheentity/_search	{     "query":{         "query_string":{             "query":"   +ManagerName:财富广场 -ManagerName:广场"         }     } }

 

过滤器

Filter 查询 Filter查询不同时支持bool、or、and、exists、missing查询	Post	http://172.16.20.49:9200/zuhe/zuheentity/_search	{  "filter":         {             "bool":             {"should":                   [{"term":{"ManagerName":"世"}}                    ,{"term":{"ManagerName":"界"}}                 ],             "must_not":                 {"term":                       {"ManagerName":"水"}                 }             }         } }
Query 语义查询	Post	http://172.16.20.49:9200/zuhe/zuheentity/_search	{  "query":         {             "bool":             {"should":                   [{"term":{"ManagerName":"世"}}                    ,{"term":{"ManagerName":"界"}}                 ],             "must_not":                 {"term":                       {"ManagerName":"水"}                 }             }         } }
Filter、query联合查询			{  "filter":         {             "bool":             {"should":                 [{"term":{"ManagerName":"世"}}                    ,{"term":{"ManagerName":"界"}}                 ],             "must":                 {"term":                       {"ManagerName":"水"}                 }             }         }         ,"query":         {             "bool":             {"should":                   [{"term":{"ManagerName":"世"}}                    ,{"term":{"ManagerName":"界"}}                 ],             "must_not":                 {"term":                       {"ManagerName":"界"}                 }             }         } }

 

高级查询：

首先建立mapping关系，表示在type1对应的文档中，包含一个obj1的对象；

{

    "type1" : {

        "properties" : {

            "obj1" : {

                "type" : "nested"

            }

        }

    }

}

嵌套查询，

{

    "query":{

    "nested" : {

        "path" : "obj1",

        "query" : {

            "bool" : {

                "must" : [

                    {

                        "match" : {"obj1.name" : "善亮"}

                    }

                ]

            }

        }

    }

}

}

父查询、子查询同样，先建立mapping关系；

Put

http://172.16.20.49:9200/testindex/

“”{

  "mappings": {

    "grouptype": {

       

        "properties" : {

          "groupid" : {

            "type" : "long"

          }

           

        }

        },

    "person": {

      "_parent": {

        "type": "grouptype"

      }

    }

  }

}

插入元素：

http://172.16.20.49:9200/testindex/person/1?parent=1

{

   

    "name":"zhan san",

    "age":"10"

}

查询父：

http://172.16.20.49:9200/testindex/grouptype/_search

{

  "query": {

    "has_child": {

      "type": "person",

      "query": {

        "match": {

          "age": 10

        }

      }

    }

  }

}

https://www.elastic.co/guide/en/elasticsearch/reference/current/mapping-parent-field.html

查询子：

http://172.16.20.49:9200/testindex/person/_search

{

  "query": {

    "has_parent": {

      "type": "grouptype",

      "query": {

        "match": {

          "groupname": "搜索组"

        }

      }

    }

  }

}

 分组统计：

{
  "query": {
    "filtered": {
      "filter": {
        "missing": {
          "field": "Zhlx"
        }
      }
    }
  },
  "size": 1,
  "aggregations": {
    "tag": {
      "terms": {
        "field": "Permit",
        "size": 20
      }
    }
  }
}
