Currently it is not possible from a simple $match query on the aggregation framework to match fields of a document that might contain the same value:
test> db.example.insert( { 'colour': 'BLUE', 'color': 'BLUE' } )
Inserted 1 record(s) in 157ms
WriteResult({
"nInserted": 1
})
test> db.example.aggregate( {$match:{ "colour": "$color" } })
{
"result": [ ],
"ok": 1
}
given the semantics of the "$" operator we should be able to support it.
