Equivalent of object.values() in mango?

[Stefan Klein]

Hi,

I'm trying to migrate an existing view to mango since this would allow for
some optimisations.
The documents contain a structure like:

"refs" : {
     "foo" : ["ABC","TFG"],
     "bar" : ["KOL","ABC"]
}
I need to find all documents where any of the arrays contain a given value,
regardless of the key (which is not known in this case).

With the existing operators it seams not to be possible to match on the
values of an object.
(A very big $or would technically possible, but that would be really ugly.)

Am I missing something?

regards,
Stefan
