title: PyMongo. How to filter the following data correctly?
body: <p>My collection is looks like:</p>
  
  <pre><code>{
      ....
      "Main":{
          ...
          "Tags":[
              "tag1",
              "tag2",
              ...
          ]
      }
  }
  </code></pre>
  
  <p>I am given a list of tags, the goal is to find all objects from the collection such that all tags from the list is in the object's list of tags. What is the correct and simplest way to do that?</p>
