Description
Using the m/r function with an $or query appears to be impossible right now. We are using the query below for one of our map reduces and are getting this error:
SyntaxError: invalid property id
|
mongo mentions line 78; below are lines 73-84:
db.runCommand({
|
mapreduce : "clients_raw",
|
map : m,
|
reduce : r,
|
query : {
|
{ "_id.DAY": "2012-06-22" , $or : [ {"_id.CLIENT_ID": 123}, {"_id.CLIENT_ID": 456} ] }
|
},
|
out : {
|
merge : "clients"
|
},
|
finalize : f
|
});

Running the query through a find generates the results we expect; removing the $or condition, too, generates results we expect. It seems as if combining $or with another field however, is not possible at this point.
