高级查询
准备数据
PUT czxy2 PUT czxy2/_mapping/user { "properties": { "username": { "type": "text", "analyzer": "ik_max_word" }, "city": { "type": "keyword" }, "age": { "type": "float" } } } PUT czxy2/user/u001 { "username": "张三", "city": "山西", "age": 18 } PUT czxy2/user/u002 { "username": "张四", "city": "山东", "age": 20 } PUT czxy2/user/u003 { "username": "张三三", "city": "山东", "age": 22 }
查询所有
match_all：检索所有的数据
GET _search { "query": { "match_all": {} } }
查询指定索引的所有
GET czxy2/_search { "query": { "match_all": {} } }
查询部分结果
GET czxy2/_search { "query": { "match_all": {} }, "_source": ["username","city"] }
条件查询：匹配查询
GET czxy2/_search { "query": { "match": { "username": "张三" } } }
条件查询：复合查询（多条件查询）
bool：多条件拼接
must：必须
must_not：不含
should：可有可无
GET czxy2/_search { "query": { "bool": { "must": [ { "match": { "city": "山东" } } ], "must_not": [ { "match": { "age": 22 } } ] } } }
should并集查询
注意：must和should同时存在的时候，should将会变得不起作用
GET czxy2/_search { "query": { "bool": { "should": [ { "match": { "city": "山东" } }, { "match": { "city": "山西" } } ] } } }
精确匹配
term 进行精确匹配（数据要求：数字、日期、布尔、not_analyzed的字符串(未分词)）
GET czxy2/_search { "query": { "term": { "age": 2 } } }
范围查询
range 用于确定范围，gt 大于、lt 小于、gte大于等于、lte小于等于
GET czxy2/_search { "query": { "range": { "age": { "gte": 19, "lte": 21 } } } }
排序
GET czxy2/_search { "query": { "match_all": {} }, "sort": [ { "age": { "order": "desc" } } ] }
分页查询
from 设置索引号，从0开始
size 设置每页个数
GET czxy2/_search { "query": { "match_all": {} }, "from": 0, "size": 1 }
