      Example collection:

      { test: [1,2,3] }
{ test: [1,3] }
{ test: [2] } 
{ test: [3,4] }

      There's no way to get element that match a subset of an array.
      It would be useful to write something like: 

      db.coll.find({ test: {$subset: [1,2,3] }})

      to extract all object except the last one (that contains '4'). It's something similar to a reversed $all operator...
