我需要查询 elasticsearch 的帮助

Question

我需要帮助查询。

这是我的查询和示例：

GET /product/_search
{
  "query": {
    "bool" : {
      "must" : {
        "multi_match" : {
          "query":    "Torsades", 
          "fields": [ "ean^10", "name^4", "brand" ] 
        }
      }
    }
  }
}

[
  {
    "_index" : "product_2022-05-13-194440",
    "_type" : "_doc",
    "_id" : "1",
    "_score" : 13.78764,
    "_source" : {
      "country" : 1,
      "ean" : "3250391967858",
      "name" : "Torsades Semi-complètes BIO - 500G",
      "brand" : "Fiorini"
    }
  },
  {
    "_index" : "product_2022-05-13-194440",
    "_type" : "_doc",
    "_id" : "74",
    "_score" : 13.78764,
    "_source" : {
      "country" : null,
      "ean" : "3564700009826",
      "name" : "Pâtes Torsades - Turini - 500 g",
      "brand" : "Turini"
    }
  },
  {
    "_index" : "product_2022-05-13-194440",
    "_type" : "_doc",
    "_id" : "78",
    "_score" : 11.964245,
    "_source" : {
      "country" : null,
      "ean" : "3250391967858",
      "name" : "Torsades Semi-complètes BIO - 500G - ITM BENCHMARK",
      "brand" : "Fiorini"
    }
  }
]

我想要一个特定的条件，但找不到解决方案：

我要：

国家/地区的所有产品=1 AND（国家/地区的所有产品=null MINUS product.ean IN country=1）

在我的样本中，我想要 2 次点击：

THIS 被删除，因为国家/地区=1 中的 EAN :

{
    "_index" : "product_2022-05-13-194440",
    "_type" : "_doc",
    "_id" : "78",
    "_score" : 11.964245,
    "_source" : {
      "country" : null,
      "ean" : "3250391967858",
      "name" : "Torsades Semi-complètes BIO - 500G - ITM BENCHMARK",
      "brand" : "Fiorini"
    }
}

有人有解决办法吗？

编辑：我想要这个结果：

[
  {
    "_index" : "product_2022-05-13-194440",
    "_type" : "_doc",
    "_id" : "1",
    "_score" : 13.78764,
    "_source" : {
      "country" : 1,
      "ean" : "3250391967858",
      "name" : "Torsades Semi-complètes BIO - 500G",
      "brand" : "Fiorini"
    }
  },
  {
    "_index" : "product_2022-05-13-194440",
    "_type" : "_doc",
    "_id" : "74",
    "_score" : 13.78764,
    "_source" : {
      "country" : null,
      "ean" : "3564700009826",
      "name" : "Pâtes Torsades - Turini - 500 g",
      "brand" : "Turini"
    }
  }
]

Answer 1

您尝试使用 Field Collapsing?

GET test/_search
{
  "query": {
    "bool": {
      "must": {
        "multi_match": {
          "query": "Torsades",
          "fields": [
            "ean^10",
            "name^4",
            "brand"
          ]
        }
      }
    }
  },
  "collapse": {
    "field": "ean.keyword"
  }
}

回复：

  "hits" : [
      {
        "_index" : "test",
        "_type" : "_doc",
        "_id" : "1",
        "_score" : 0.5611319,
        "_source" : {
          "country" : 1,
          "ean" : "3250391967858",
          "name" : "Torsades Semi-complètes BIO - 500G",
          "brand" : "Fiorini"
        },
        "fields" : {
          "ean.keyword" : [
            "3250391967858"
          ]
        }
      },
      {
        "_index" : "test",
        "_type" : "_doc",
        "_id" : "2",
        "_score" : 0.5611319,
        "_source" : {
          "country" : null,
          "ean" : "3564700009826",
          "name" : "Pâtes Torsades - Turini - 500 g",
          "brand" : "Turini"
        },
        "fields" : {
          "ean.keyword" : [
            "3564700009826"
          ]
        }
      }
    ]
