Waterline (Sails.js): AND conditions

Question

I'm using mongodb with sails.js querying a model that contains the titles of torrent files. But I'm not able to perform a waterline query using the "AND" condition. I've already tried it in several ways but most of them return empty or simply, never return.

e.g. the database contains an entry with: "title": "300 Rise Of An Empire 2014 720p BluRay x264-BLOW [Subs Spanish Latino] mkv"

When adding each query parameter line by line:

var query = Hash.find();
query = query.where({ "title": { "contains": "spanish" } });
query = query.where({ "title": { "contains": "2014" } });
query = query.where({"or": [ { "title": { "contains": "720p" } }, { "title": { "contains": "1080p" } } ] });

It returns entries containing "2014" AND ("720p" OR "1080p"), some of them also contain "spanish" but I think it's just a coincidence.

How can I specify "spanish" AND "2014" AND ("720p" OR "1080p)?

Thanks!

There is a solution but it's really a mongo one :

query = query.where({"$and": [ { "title": { "contains": "720p" } }, { "title": { "contains": "1080p" } } ] });

Notice the $and key?
