如何在弹性搜索中使用 DSL QUERY 验证输入值是否在范围内

Question

我有两个实体，例如 User & Activity。 Activity 包含像 ["10:20","25:30"] 这样的归档年龄组和包含年龄字段的用户实体。考虑到用户年龄是 26 岁，所以 he/she 符合 activity 的条件。我想获取所有满足上述条件的活动

GET _search
{
"query": {

    "bool": {
        "filter": {
          "range": {
            "ageGroup": {
              "gte": 50,
              "lte": 55
            }
          },
          "term": {"****": "M"}
        },  
      "must": [
        {
          "term": {"******": {"value": "15"}}

        }
      ] ,"should": [
               {
                   "match": {"******": "7"}
               },
               {
                   "match": {"******": "1"}
               }
            ]
    }
 }
}

Answer 1

包括(Entity/Object)包含列表

public class Include {
@Field(type= FieldType.Nested)
private List<AgeGroup> age;
}

数据： {......, include.age:{ "id": 4, "minAge": 4, "maxAge": 9 }, { "id": 3, "minAge": 1, "maxAge": 4 }, .....}

DSL 查询：

GET /_search
    {
        "query": {

         "bool": {
           "should": [
                {"range": {"include.age.minAge": {"lte": 9}}},
                {"range": {"include.age.maxAge": {"gte": 9}}
                }
              ],"minimum_should_match": 2
         } 

        }
    }

您还可以使用 integer_range 数据类型来验证值是否在范围内 https://www.elastic.co/guide/en/elasticsearch/reference/current/range.html
