搜索：

{
    nid: 10582,
    keywords: {"$in": ['turk']}             
}

结果：没有！

我做错了什么？

Answer 1

答案很简单：因为关键字不是数组。要搜索关键字，您需要更改文档结构，如下所示：

{
...
"keywords": [
     "bob",
     "smith",
     "123",
     "turk",
     "hill",
     "rd",
     "14450" 
  ],
...
}

通常在您从驱动程序序列化字典时发生。在目前的时刻，没有办法搜索这样的结构。简单使用数组而不是字典。或者您可以在序列化文档之前将字典转换为数组，反之亦然，在反序列化文档时。

mongo搜索没有关键字
