elasticsearch - Elasticsearch多个查询有限制

Question

我正在尝试编写一个Elasticsearch查询，其中我在标题和描述中匹配多个单词。下面的代码可以正常工作，但是提供了所有与这些单词匹配的文章。我的目标是每个查询字词需要4篇文章，例如蒂姆·库克的4个结果和史蒂夫·乔布斯的四篇文章

{
  "query": {
        "multi_match": {
            "query":   ["Tim Cook","Steve Jobs"],
            "fields": ["Title", "Description" ],
            "operator":"AND"
         }
  }
}

Answer 1

Top hits aggregations是您的寻找-
基本上给2个filter aggregation，然后在它们旁边嵌套热门匹配。

所以下面的东西应该可以正常工作

{
  "size": 0,
  "query": {
    "multi_match": {
      "query": [
        "Tim Cook",
        "Steve Jobs"
      ],
      "fields": [
        "Title",
        "Description"
      ],
      "operator": "AND"
    }
  },
  "aggs": {
    "tim": {
      "aggs": {
        "top_hits": {}
      },
      "filter": {
        "query": {
          "multi_match": {
            "query": [
              "Tim Cook"
            ],
            "fields": [
              "Title",
              "Description"
            ],
            "operator": "AND"
          }
        }
      }
    },
    "steve": {
      "aggs": {
        "top_hits": {}
      },
      "filter": {
        "query": {
          "multi_match": {
            "query": [
              "Steve Jobs"
            ],
            "fields": [
              "Title",
              "Description"
            ],
            "operator": "AND"
          }
        }
      }
    }
  }
}
