Answer 1

For this you can add a regular expression to each item in the array, you can do it in the following way.

data = ['hoLA','Que','TAL', 'Nueva'];
data  = data.map(function(v, i){return new RegExp(v, 'i')});
MyCollection.find({"thing": {$in : data}}, function(err, data){
    if (err) {
        console.log(err)
    }else{
        data.forEach(function(item){
            console.log(item.nombre);
        })
    }
});
