将数组与 ELASTICSEARCH 中的数组字段匹配

Question

我在存储目录的 ES 中有一个索引。文档是字符串和数组类型的混合（示例如下所示）：

{
  "_index" : "catalog",
  "_type" : "_doc",
  "_id" : "N1234",
  "_score" : 1.0,
  "_source" : {
    "product_id" : "1234",
    "name" : "Multifunctional Soapbox Hanging",
    "model" : "HS-11",
    "image" : "catalog/1.jpg",
    "size" : [
      "43",
      "44",
      "45"
    ],
    "color" : [
      "66",
      "67"
    ],
    "tag" : [
      "Soap Dish Rack Bathroom Essentials",
      "Plastic Bathroom Essentials",
      "Adhesive Bathroom Essentials",
      "Smart Accessories Bathroom Essentials",
      "Any Bathroom Essentials",
      "Brown Bathroom Essentials",
      "Bathroom Accessories Bathroom Essentials",
      "Bathroom Essentials"
    ],
    "language_id" : "1",
    "status" : "7",
    "date_added" : "2021-02-06 14:29:37"
  }
}

所有文档都是相同的结构。我想根据 Color 和 Tag 字段查询类似产品的索引。意思是，如果我通过 color = 66 和 Tag = [ARRAY_OF_VALUES]，它应该 return 我最相似的产品按分数排序，可能包含相同的颜色或最大匹配的标签。

我尝试 BOOL 使用 Should 或 Must 进行查询，但没有更好的结果。

我不知道如何查询数组，因为颜色和标签都是数组。我应该将 TAGS 参数作为数组或单独的值传递并进行单独的 match 查询吗？

我试过的查询（@ESCoder）：

"query": {
"bool": {
  "must": [
    {
      "terms": {
        "color": [
          "40" //code of blue color
        ]
      }
    }
  ],
  "should": [
    {
      "terms": {
        "tag": [
          "Casual Dresses",
          "Round Neck Dresses",
          "Short Sleeves Dresses",
          "Blue Dresses"
        ]
      }
    }
  ]
}

}

预期结果：

包含相同 color 和最大相似度 tag 的所有产品，按得分排序

{
  "_index" : "catalog",
  "_type" : "_doc",
  "_id" : "N624121",
  "_score" : 39.43454,

Answer 1

您可以使用 terms query 搜索多个值。

术语查询 returns 文档在提供的字段中具有确切的术语（此处 tag）。

如果您没有明确定义任何映射，则需要将 .keyword 添加到 tag 字段。这使用关键字分析器而不是标准分析器（注意 tag 字段后的“.keyword”）。

试试下面的查询

    {
  "query": {
    "bool": {
      "must": [
        {
          "terms": {
            "color": [
              "40" //code of blue color
            ]
          }
        },
        {
          "terms": {
            "tag.keyword": [
              "Casual Dresses",
              "Round Neck Dresses",
              "Short Sleeves Dresses",
              "Blue Dresses"
            ]
          }
        }
      ]
    }
  }
}

搜索结果将包含得分为 2.0 的所有文档

但是如果你想根据分数排序，那么你需要使用 bool/should 子句和 term 查询

{
  "query": {
    "bool": {
      "must": [
        {
          "terms": {
            "color": [
              "40" //code of blue color
            ]
          }
        }
      ],
      "should": [
        {
          "term": {
            "tag.keyword": "Casual Dresses"
          }
        },
        {
          "term": {
            "tag.keyword": "Round Neck Dresses"
          }
        },
        {
          "term": {
            "tag.keyword": "Short Sleeves Dresses"
          }
        },
        {
          "term": {
            "tag.keyword": "Blue Dresses"
          }
        }
      ],
      "minimum_should_match": 1
    }
  }
}

搜索结果将是
