How to choose the most appropriate documents for a query in mongo?

Question

MongoDB

In general, a question was asked at an interview a long time ago, I thought I’d come and google it, but I came and forgot.
Now I remembered. The essence of the question was something like this, they say there are collections with articles, the article has tags.
It is necessary to make a request in the mongo console, which would display the titles of the articles in order, which are the closest tags in the search.
Well, for example, there are tags in the request: "obama, bananas, sanctions, dzhigurda."
And there are articles with titles and tags: "Obama eats bananas", "Dzhigurda imposed sanctions", "Putin rejected sanctions", "Obama and Dzhigurda eat bananas". Well, there the tags are probably the same, separated by commas. I don’t remember exactly the syntax, and it’s not the essence of what you need to read. To make search queries for the closest values ​​\u200b\u200bfor the parameters? And to make a nodo with a request to the console,
Chaotically described, but I think you understand.
