Answer 1

Try

find({
    'Categories.brandname':'Nokia', 
    'Categories.models.name':'Lumia', 
    'Categories.models.submodel.name':
        {'$all':['Lumia 510', 'Lumia 735 TS']}
})

$all will give you stores that sell both Lumia 510 and Lumia 735. if you need query that selects either one of these models, use $in instead.
