      Currently $elemMatch can only be applied to an array. For example { a:{ $elemMatch:{ $gte:1, $lte:10 } } } will match { a:[ 5 ] } but not { a:5 }. This is a bit awkward in a case like { 'a.b':{ $elemMatch:{ $gte:1, $lte:10 } } } and a document { a:[ { b:5 }, { b:15 } ] }. The document will not match because the b values are not arrays, even though there could be multiple values of 'a.b'.
