sorting - Elasticsearch:按条件匹配的字段对某些项目进行排序，其他按条件进行排序

Question

假设我有一个这样映射的文档:

{
  "corp" : {
    "mappings" : {
      "staff" : {
        "properties" : {
          "created" : {
            "type" : "date",
            "format" : "dateOptionalTime"
          },
          "name" : {
            "type" : "string"
          },
          "public" : {
            "type" : "boolean"
          },
          "salary" : {
            "type" : "long"
          }
        }
      }
    }
  }
}

像这样的数据集:

[{"name": "John", "salary": 100000, "public": true, "created": "<datestamp>"},
 {"name": "Bob", "salary": 80000, "public": false, "created": "<datestamp>"},
 {"name": "Wendy", "salary": 110000, "public": true, "created": "<datestamp>"},
 {"name": "Joan", "salary": 210000, "public": false, "created": "<datestamp>"}]

我想构造一个排序，使我们仅在public=true处按薪水排序，然后通过created字段对其余项目进行排序。最终结果应为:

went

约翰

Bob(取决于created日期)​​

琼(取决于created日期)​​

这可能吗？

Answer 1

应该这样做:

GET /corp/staff/_search
{
  "sort": [
    {
      "public": {
        "order": "desc"
      }
    },
    {
      "salary": {
        "order": "asc"
      }
    },
    {
      "created": {
        "order": "asc"
      }
    }
  ]
}
