javascript - Waterline query of arrays separated "OR" -

i'm trying sails backend rest call retrieves me items either "country" column or "subcountry" column matches array have. i've tried:

{     skip: 0,     where: {         or: [             {country: ['argentina', 'brasil']},             {subcountry: ['argentina', 'brasil']}         ]     } } 

but return 0 records.

looks problem have implicit "in" on each "or" term. i'm querying mongo database.

it's not "pretty" idea, since $in $or shorter notation form still should able long notation form same:

{     "where": {         "or": [             { "country": "argentina" },             { "country": "brasil" },             { "subcountry": "argentina" },             { "subcountry": "brasil" }         ]     } } 

alternately can accept using "native" query form instead:

model.native(function(err,collection) {     collection.find({         "$or": [             { "country": { "$in": [ "argentina", "brasil" ] } },             { "subcountry": { "$in": [ "argentina", "brasil" ] } },         ]     }).toarray(function(err,docs) {      }); }); 

since there nothing wrong query form itself, how being serialized mongodb waterline.
