笔记参考：

https://note.youdao.com/ynoteshare/index.html?id=dc7be4dfa0d34d984223d4b87139b9c2&type=note&_time=1631514908776

range 查询和 exists 查询

prefix 查询

wildcard 查询和 regexp 查询

这些查询都可以用在组合查询中

简单查询不用 must，term相当于等号

post /product_db/_search
{
"from": 0,
"size": 10,
"query": {
"term": {
"categoryId": 19
}
}
}

例子1：根据时间范围和用户Id查询

must 相当于and

get voucher_record_form/_search
{
"from": 5,
"size": 5,
"query": {
"bool": {
"must": {
"range": {
"createTime": {
"gte": 1601091496,
"lte": 1601609835
}
}
},
"filter": [
{
"term": {
"useUid": 2583692
}
}
]
}
},
"sort": [
{
"_id": "desc"
}
]
}

实现：查询用户ID为？，并且按时间查询
get voucher_record_form/_search
{
"from": 0,
"size": 5,
"query": {
"bool": {
"must": {
"term" : {"createTime": 1601177491}
},
"filter": [
{
"term": {
"useUid": 2583692
}
}
]
}
},
"sort": [
{
"_id": "desc"
}
]
}

实现：查询用户ID为？，并且按时间查询
get voucher_record_form/_search
{
"from": 0,
"size": 5,
"query": {
"bool": {
"must": [

{
"term" : {"createTime": 1601177491}
} ,

{
"term": {
"useUid": 2583692
}
}
]
}
},
"sort": [
{
"_id": "desc"
}
]
}

查询结果如sql语句中的： isDeal =0 and (uid=1235 or isGlobal=1) 先 and 再 or 查询

must里面再包含bool查询,相当于子查询，里面的bool中的should相当于or查询

POST /message/_search
{
   "query": {
       "bool": {
           "must": [
               {
                   "match": { "isDeal": false }
               },
               {
                   "bool": {
                       "should": [
                           { "match": { "uid": 1448626 } },
                           { "match": { "isGlobal": true } }
                       ]
                   }
               }
           ]
       }
   }
}

should里面用term也行，term为精确查询 match为模糊查询

multi_match 查询

多个字段上执行匹配相同的查询，叫做"multi_match"查询。比如：

POST /kibana_sample_data_flights/_search

{

"query": {

"multi_match": {

"query":"AT",

"fields":["DestCountry", "OriginCountry"]

}

post /message/_search
{"query":{"bool": {"must": [{"match": {"isDeal": false }},{"bool":{"should":[{"term":{"uid":1448626}},{"term":{"isGlobal":true}}]}}]}}
}

相当于sql ： select * from message where isDeal=false and (uid=1448626 or isGlobal = true)

bool组合查询可用的布尔类型子句包括must、filter、should 和must_not 四种，它们接收参数值的类型为数组。
must 查询结果中必须要包含的内容，影响相关度
filter 查询结果中必须要包含的内容，
不会影响相关度 should 查询结果非必须包含项，
包含了会提高分数，影响相关度 must_not 查询结果中不能包含的内容，不会影响相关度

must 相当于 and

should 相当于 or

must_not 相当于not

当 should 子句与 must 子句或 filter 子句同时出现在子句中时，should 子句将不会过滤结果(should失效)

参考：

elasticsearch7常见查询（term、match、bool、filter）_未知的风fly-CSDN博客_elasticsearch7 查询

相当于Mysql中的多个and查询

term为精确查询 match为模糊查询，分页查询条数

POST /message/_search
{
   "query": {
       "bool": {
           "must": [
                   {"match": {"receiveShopId": 14950828}},
                      {"match": { "isDeal": false } },
                      {"match": { "type": 28 }}
           ]
       }
   }
}

POST /message/_search
{
"from":0,
"size":20,
   "query": {
       "bool": {
           "must": [

                   {"term": {"receiveShopId": 14950828}},
                       {"term": { "isDeal": false } },
                       {"term": { "type": 28 }}

           ]
       }
   }
}

.1 创建索引库

put product_db

第4步属性嵌套查询

post /product_db/_search
{"from": 0,"size": 10,"query": {"bool": {"must": [{"match": {"name": "手机"}}],"filter": [{"term": {"hasStock": true}},{"range": {"price": {"from": "1","to": "5000"}}}]}},"sort": [{"salecount": {"order": "desc"}}],"aggs": {"brand_aggs": {"terms": {"field": "brandId","size": 10},"aggs": {"brand_name_aggs": {"terms": {"field": "brandName"}},"brand_img_aggs": {"terms": {"field": "brandImg"}}}},"category_aggs": {"terms": {"field": "categoryId","size": 10},"aggs": {"cate_name_aggs": {"terms": {"field": "categoryName"}}}},"attrs_aggs": {"nested": {"path": "attrs"},"aggs": {"attr_id_aggs": {"terms": {"field": "attrs.attrId"},"aggs": {"attr_name_aggs": {"terms": {"field": "attrs.attrName"}},"arrt_val_aggs": {"terms": {"field": "attrs.attrValue"}}}}}}},"highlight": {"pre_tags": ["<b style='color:red'>"],"post_tags": ["</b>"],"fields": [{"name": {}}]}
}

在 must里面可以搜索分类ID不过性能没有Filter里面的好

在filter里面也能用

嵌套nested组合查询

post /product_db/_search
{"from": 0,"size": 10,"query": {"nested": {"path": "attrs","query": {"bool": {"must": [{"term": {"attrs.attrId" : 9}}]}}}}
}

非组合查询用下面这段就行了

post /product_db/_search
{"from": 0,"size": 10,"query": {"nested": {"path": "attrs","query": {"term": {"attrs.attrId": 9}}}}
}

post /product_db/_search
{"from": 0,"size": 10,"query": {"bool": {"must": [{"match": {"name": "手机"}},{"nested": {"path": "attrs","query": {"bool": {"must": [{"term": {"attrs.attrId": 9}}]}}}}],"filter": [{"term": {"hasStock": true}},{"term": {"categoryId": 19}},{"term": {"brandId": 59}},{"range": {"price": {"from": "1","to": "5000"}}}]}},"sort": [{"salecount": {"order": "desc"}}],"highlight": {"pre_tags": ["<b style='color:red'>"],"post_tags": ["</b>"],"fields": [{"name": {}}]}
}

非组合查询用下面这段就行了

post /product_db/_search
{"from": 0,"size": 10,"query": {"bool": {"must": [{"match": {"name": "手机"}},{"nested": {"path": "attrs","query": {"term": {"attrs.attrId": 9}}}}],"filter": [{"term": {"hasStock": true}},{"term": {"categoryId": 19}},{"term": {"brandId": 59}},{"range": {"price": {"from": "1","to": "5000"}}}]}},"sort": [{"salecount": {"order": "desc"}}],"highlight": {"pre_tags": ["<b style='color:red'>"],"post_tags": ["</b>"],"fields": [{"name": {}}]}
}
