Multiple criteria possible in one query inside MongoDB?

I've a "words" collection in MongoDB. When I want to search the collection I want to list first words that starts with the "word" and then contains the "word" that I querid. In the same array I get this result; "simarte", "Cumartesti", "Mart", "marti", "martilar". When I search with contains it brings me other words that contains the "word" (mart).

I want to order first the words that starts with the "word" than order "contains" the words. Is it possible to do that in one query? I don't want to make a second request to db.

Here is my code sample:

    var word = "mart";
    db.words.find({"w" : {$regex : ".*" + word + ".*"}}, function(err, words) {
      if( err || !words) console.log("No data found");
      else{
       res.render('index', { title: 'Words', word_data: words, word : word });
     }
    });
