Mongo db atlas search：在嵌入式文档上创建 atlas 搜索索引

Question

为了存储类别，我有以下架构 -

{
    name: String,
    description : String,
    subCategories:[
      { 
          name:String,
          description : String
      }
    ]
}

对于搜索，需要在类别名称和子类别名称上应用图集搜索索引。我尝试了以下映射，它对子类别的名称和描述不起作用。

{
  "mappings": {
    "dynamic": false,
    "fields": {
      "name": {
          "analyzer": "lucene.standard",
          "type": "string"
        },
      "description": {
          "analyzer": "lucene.standard",
          "type": "string"
        },
      "subCategory.name": {
          "analyzer": "lucene.standard",
          "type": "string"
      },
      "subCategory.description": {
          "analyzer": "lucene.standard",
          "type": "string"
      }
    }
  }
}

我在字段映射中遗漏了什么吗？

Answer 1

我在这个地图集搜索文档中找到了我这个问题的答案：

https://docs.atlas.mongodb.com/reference/atlas-search/index-definitions/

因此，我参考此文档所做的是，稍微修改我的映射以支持我的期望。我之前做错了。

{
  "mappings": {
    "dynamic": false,
    "fields": {
      "name": {
          "analyzer": "lucene.standard",
          "type": "string"
        },
      "description": {
          "analyzer": "lucene.standard",
          "type": "string"
        },
      "subCategory": {
        "fields": {
          "name": {
            "analyzer": "lucene.standard",
            "type": "string"
          },
          "description": {
            "analyzer": "lucene.standard",
            "type": "string"
          }
        }
      }
    }
  }
}

这是对文档或对象进行 Atlas 搜索的工作代码。

mainSubscriber -> object (dataType)

主订阅者的类型必须是'document'。然后你可以指定内部字段如下。

更多细节请参考文档中的静态地图示例 https://docs.atlas.mongodb.com/reference/atlas-search/index-definitions#std-label-index-config-example

{
  "mappings": {
    "dynamic": false,
    "fields": {
      "identifier": {
        "analyzer": "lucene.standard",
        "type": "string"
      },
      "mainSubscriber": {
        "fields": {
          "identifier": {
            "analyzer": "lucene.standard",
            "type": "string"
          }
        },
        "type": "document"
      },
      "profileId": {
        "analyzer": "lucene.standard",
        "type": "string"
      }
    }
  }
}
