Checking a false value in Meteor MongoDb

I'm trying to make a filtered search module with meteor. I want my users to precise their serach by adding filters.

With this :

if(!options.natives.length)
        return Meteor.users.find({
            'profile.languages.learning': {$in: options.learning}
    });
    else if(!options.learning.length)
        return Meteor.users.find({
            'profile.languages.native': {$in: options.native}
        });
    else if(!options.learning.length && !options.native.length)
        return null;
    else
        return Meteor.users.find({
            $or: [
                {'profile.languages.native': {$in: options.natives}},
                {'profile.languages.learning': {$in: options.learning}}
            ]
        });
return Meteor.users.find({
      $and: [
        {$or {'profile.languages.native': {$in: options.natives}}, NoMatchingLang},
        {'profile.languages.learning': {$in: options.learning}}
      ]

My problem is that profile.languages.learning is an array, and I want that at least ONE of it's row matches {$in: options.learning}.

What do you think is the best way to do so ?

Thanks, David

This is actually already handled by $in per the Mongo Docs - if the field contains an array, the selector will match documents that have at least one element matching across both arrays.
