【问题描述】：

现在我将一个巨大的 json yelp review 文件导入到我在 Linux 上的 mongodb 数据库中。我想实现搜索关键字的正确方法，因此我可以在“text”下查找关键字“UFC”，在属性下查找“Alcohol：full_bar”。

这是我目前所拥有的：

db.yelp.find({
  $or: [{
    "text": UFC /.*enjoy.*/i
  }, {
    "attributes": Alcohol: full_bar/.*good.*/i
  }]
})

这是我的 json 文件的示例：

【解决方案1】：

首先，您应该为text 和attributes 字段创建一个text index。

db.yelp.createIndex({ text: "text", attributes: "text" })

搜索本身应该使用$text 运算符来执行。

db.yelp.find({ $text: { $search: "UFC \"Alcohol: full_bar\"" } })

请参阅docs 了解更多信息。
