12、Elasticsearch文档多条件查询(十二)

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""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床上用品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

                }
            },
            {
   
     
                "_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)",

                }
            }
        ]
    }
}

响应的条件只有2条了,过滤掉了价格低与500的。
