Question

我正在尝试编写一个mongo查询来返回与cat1和cat2源完全相同的电子邮件的文档。

请帮忙。我包含一个带有预期匹配文档的样本集合模式

样品采集

{
        "id" : "1",
        "name" : "John",
        "contacts" : [
                {
                        "type" : "email",
                        "source": "cat1",
            "detail": aa@yahoo.com
                },
                {
                        "type" : "email",
                        "source": "cat1",
            "detail": john@yahoo.com
                },
                {
                        "type" : "email",
                        "source": "cat2",
            "detail": john@yahoo.com
                }
        ]
},
{
        "id" : "2",
        "name" : "Bell",
        "contacts" : [
                {
                        "type" : "email",
                        "source": "cat1",
            "detail": jj@yahoo.com
                },
                {
                        "type" : "email",
                        "source": "cat2",
            "detail": john@yahoo.com
                }
        ]
},

{
        "id" : "3",
        "name" : "Sam",
        "contacts" : [
                {
                        "type" : "email",
                        "source": "cat1",
            "detail": exmaple@yahoo.com
                },
                {
                        "type" : "email",
                        "source": "cat3",
            "detail": exmaple@yahoo.com
                }
        ]
}

预期结果如下：因为这是来自源cat1和cat2的公共电子邮件地址为john@yahoo.com的文档。

不应返回ID为2的文档，因为虽然它们都有来自cat1和cat2源的电子邮件，但电子邮件地址却不同。

不应返回ID为3的文档，因为通过电子邮件地址相同，其类别不是cat1和cat2。

{
        "id" : "1",
        "name" : "John",
        "contacts" : [
                {
                        "type" : "email",
                        "source": "cat1",
            "detail": aa@yahoo.com
                },
                {
                        "type" : "email",
                        "source": "cat1",
            "detail": john@yahoo.com
                },
                {
                        "type" : "email",
                        "source": "cat2",
            "detail": john@yahoo.com
                }
        ]
}

请尝试使用纯JavaScript代码过滤来自cat1和cat2的同一封电子邮件。

   public class gameWindow extends JFrame {

     public gameWindow() {

add(new SashaOhayonSnakeFST());
setResizable(false);
pack();
setLocationRelativeTo(null);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
     }


     public static void main(String[] args) {

EventQueue.invokeLater(new Runnable() { //Creates queue to run events
  public void run() {          //runs these events on new window 
    JFrame finalWindow = new gameWindow();
    finalWindow.setVisible(true);  
    finalWindow.setBackground(new Color (0,0,0,0));





  }
});
     }
   }

当子文档数组包含公共数据时，Mongo查询返回文档
