多条件查询
同时满足must
查询的body体的查询不能在使用match关键字了，而需要使用，bool然后要多个条件同时成立，接下来要填入must，多个条件用数组。body样例如下：
{
"query":{
"bool": {
"must":[
{
"match":{
"category":"床上用品"
}
}
]
}
}
}
以上看起来就相当于是单条件要一样的效果。然后我们再加一个条件。如下：
{
"query":{
"bool": {
"must":[
{
"match":{
"category":"床上用品"
}
},
{
"match":{
"price":169.0
}
}
]
}
}
}
返回结果:
{
"took": 17,
"timed_out": false,
"_shards": {
"total": 1,
"successful": 1,
"skipped": 0,
"failed": 0
},
"hits": {
"total": {
"value": 1,
"relation": "eq"
},
"max_score": 1.7292862,
"hits": [
{
"_index": "shopping",
"_type": "_doc",
"_id": "1001",
"_score": 1.7292862,
"_source": {
"title": "水星家纺被子夏季空调被 夏凉被夏天被子双人夏被被芯学生宿舍被子200*230cm",
"category": "床上用品",
"image": "https://img11.360buyimg.com/n7/jfs/t1/191056/14/24248/144443/62767f75E23ccafc4/5110691845cfa4cf.jpg",
"price": 169.0
}
}
]
}
}
返回结果就同时满足了"category":"床上用品"和"price":169.0。
部分满足should
部分满足类似于sql语句中的or.
比如我们要查category为床上用品和3C数码的.
{
"query":{
"bool": {
"should":[
{
"match":{
"category":"床上用品"
}
},
{
"match":{
"category":"3C数码"
}
}
]
}
}
}
操作如下
范围条件filter
比如我期望查询的是价格在500以上的产品。
查询内容体：
{
"query":{
"bool": {
"should":[
{
"match":{
"category":"床上用品"
}
},
{
"match":{
"category":"3C数码"
}
}
],
"filter":{
"range":{
"price":{
"gt":500
}
}
}
}
}
}
操作结果
响应内容：
{
"took": 5,
"timed_out": false,
"_shards": {
"total": 1,
"successful": 1,
"skipped": 0,
"failed": 0
},
"hits": {
"total": {
"value": 2,
"relation": "eq"
},
"max_score": 3.1789374,
"hits": [
{
"_index": "shopping",
"_type": "_doc",
"_id": "1003",
"_score": 3.1789374,
"_source": {
"title": "华为手机",
"category": "3C数码",
"image": "https://img10.360buyimg.com/n7/jfs/t1/111175/35/24913/81730/625ed1a5Ed8f452a3/d0370cd4e6837908.jpg",
"price": 1699.0
}
},
{
"_index": "shopping",
"_type": "_doc",
"_id": "1002",
"_score": 1.8126037,
"_source": {
"title": "水星家纺 60S长绒棉贡缎床上四件套 酒店高档纯棉床单被套枕套 被罩被单1.8米床乔伊斯玫瑰(海蓝色/抗菌)",
"category": "床上用品",
"image": "https://www.shuixing.com/pc/images/2022/logo_02.png",
"price": 899.0
}
}
]
}
}
响应的条件只有2条了，过滤掉了价格低与500的。
