#30 MIM Doesn't support $elemMatch in $all

[Daryll Strauss]

MIM doesn't support $elemMatch in an $all query.

http://docs.mongodb.org/manual/reference/operator/query/all/

Example:

db.inventory.find( {
                 qty: { $all: [
                                { "$elemMatch" : { size: "M", num: { $gt: 50} } },
                                { "$elemMatch" : { num : 100, color: "green" } }
                              ] }
               } )

Here's my fix in Match.match:

    if op == '$all':
        for ele in value:
            if type(ele) == dict and '$elemMatch' in ele:
                if not self.match(key, '$elemMatch', ele['$elemMatch']):
                    return False
            else:
                if not self.match(key, '$eq', ele):
                    return False
        return True

This still appears to be relevant for version 0.5.2
