複数のフィールドを持つMongoDBテキスト検索重複結果セット

Question

私の製品コレクションにテキストインデックスがあります。このインデックスは、以下に示すように異なる重みを持つ3つの列を使用します。私が検索すると「りんご」と言えば、同じ商品が何回も返されることがわかります。しかし、1つの製品だけではなく、ほとんどの製品が複製されています。これは何が原因でしょうか？コレクションのインデックスを再作成する必要がありますか？ おかげ

{ 
    "v": 1, 
    "key": { 
     "_fts": "text", 
     "_ftsx": 1 
    }, 
    "name": "searchCollection", 
    "ns": "local.product", 
    "weights": { 
     "categoryList": 3, 
     "productInformation": 1, 
     "title": 5 
    }, 
    "default_language": "english", 
    "language_override": "language", 
    "textIndexVersion": 2 
} 

これは結果である：

Answer 1

問題がsailsjsから.native（）を使用することによって引き起こされました。これを使うと、システムはモデルを返さず、代わりに配列を返します。その配列内のオブジェクトはオブジェクト（objectId）として指定されたIDフィールドを持たないため、関連する文書（カート）にレコードを挿入する前に、それらを新しい製品と見なして製品コレクションに挿入します。文字列IDを使って製品ドキュメントを削除し、idフィールドの追加チェックをアプリに追加することで問題は解決されました。
