      Current ABTs fail to match {a: []} when doing db.find({a: {$lte: MaxKey()}). The desired behavior of db.find({a: {$lte: MaxKey()}) should return any and all document, with the field 'a'.

      The suspect issue arises when we choose to traverse the array and make a compare between each element and MaxKey() .

      Instead, the array itself should be compared to MaxKey(), as an empty array satisfies the $lte: MaxKey() requirement. Similar behavior should also be implemented when comparing to MinKey().
