命令

查询所有索引	GET /_cat/indices GET /_cat/indices?v
创建索引	PUT /user
删除索引	DELETE /user
添加文档
删除文档
查询文档	GET /user/_search
name字段包含"张三"或"李四"的	GET /user/_search { "query": { "match":{"name": "张三李四"} }, "from": 0, "size": 20, "_source": ["name"] }
匹配所有文档	GET /user/_search { "query": { "match_all":{} } }
所有name字段，包含"张三"的	GET /user/_search { "query": { "match_phrase":{"name": "张三"} } }
bool查询所有数据中，name字段同时包含"张三"、"李四"的	GET /user/_search { "query": { "bool": { "must": [ {"match": {"name": "张三"}}, {"match": {"name": "李四"}}, ], } } }
bool查询所有数据中，name字段包含"张三"或"李四"的	GET /user/_search { "query": { "bool": { "should": [ {"match": {"name": "张三"}}, {"match": {"name": "李四"}}, ], } } }
bool查询所有数据中，name字段同时不包含"张三"也不包含"李四"的	GET /user/_search { "query": { "bool": { "must_not": [ {"match": {"name": "张三"}}, {"match": {"name": "李四"}}, ], } } }
bool查询所有数据中，name字段包含"张三"，但不包含"李四"的	GET /user/_search { "query": { "bool": { "must": [ {"match": {"name": "张三"}}, ], "must_not": [ {"match": {"name": "李四"}}, ], } } }
过滤查询所有数据中，10<=age<=20的	GET /user/_search { "query": { "bool": { "must": [ {"match_all": {}}, ], "filter": { "range": {"age": {"gte":10, "lte": 20}} } } } }
聚合查询根据state分组，倒序，统计state、count(id) 等同于: SELECT state, COUNT() FROM bank GROUP BY state ORDER BY COUNT() DESC 说明： size=0 是为了不要查询文档，只要聚合结果	GET /user/_search { "size": 0, "aggs": { "group_by_state": { "terms": { "field": "state.keyword" } } } }
聚合查询根据state分组，倒序，统计state、 count(id)、avg(balance) 等同于: SELECT state, COUNT(), avg(balance) FROM bank GROUP BY state ORDER BY COUNT() DESC	GET /user/_search { "size": 0, "aggs": { "group_by_state": { "terms": { "field": "state.keyword" }, "aggs": { "average_balance": { "avg": { "field": "balance" } } } } } }
聚合查询根据state分组，balance平均值倒序，统计state、 count(id)、avg(balance) 等同于: SELECT state, COUNT(*), avg(balance) FROM bank GROUP BY state ORDER BY avg(balance) DESC	GET /user/_search { "size": 0, "aggs": { "group_by_state": { "terms": { "field": "state.keyword", "order": { "average_balance": "desc" } }, "aggs": { "average_balance": { "avg": { "field": "balance" } } } } } }
聚合查询根据age年龄段分组，然后按照性别分组，然后获取balance平均值	GET /user/_search { "size": 0, "aggs": { "group_by_age": { "range": { "field": "age", "ranges": [ { "from": 20, "to": 30 }, { "from": 30, "to": 40 }, { "from": 40, "to": 50 } ] }, "aggs": { "group_by_gender": { "terms": { "field": "gender.keyword" }, "aggs": { "average_balance": { "avg": { "field": "balance" } } } } } } } }
