Norman,
Your best bet would be to emit something that flags that the property
doesn't exist. Perhaps something like:
emit(doc.a || null, null)
And then query for key=null
Granted that munges when doc.a is null. To be complete you'd need to
do something like:
if(doc.a !== undefined) {
emit([doc.a], null):
} else {
emit(null, null);
}
HTH,
