我的产品集合上有一个文本索引。该索引使用具有不同权重的 3 列，如下所示。当我搜索让我们说“苹果”时，我看到多次返回相同的产品。但是，它不仅适用于一种产品，而且大多数产品都是重复的。这可能是什么原因？我需要重新索引我的收藏吗？谢谢

{
    "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
}

这是结果：

该问题是由使用sailsjs 中的.native() 引起的。当我使用它时，系统不会返回模型，而是返回一个数组。由于该数组中的对象没有将其 id 字段指定为对象 (objectId)，因此系统将它们视为新产品，并在将记录插入相关文档 (cart) 之前将它们插入产品集合中。删除带有字符串 id 的产品文档并在应用程序中添加额外的 id 字段检查解决了该问题。
