i know this is currently unsupported (and may be more of a question for the
dev list), but is there a technical reason while multi-range queries can't
be submitted to couch (slight ah-hah moment at the end)?
the specific problem i'm trying to address is this:
suppose i have a message document, and a corresponding map function:
function (doc) {
if (doc.docType != 'message') return;
emit(doc.owner, null);
}
if i wanted to pull back all messages for users foo and bar, i'd simply do a
POST path/to/couch keys = ['foo', 'bar']. now let's make this data come back
sorted by create date:
function (doc) {
if (doc.docType != 'message') return;
emit([doc.owner, doc.createDate], null);
}
also cool, but now, to retrieve all messages pertaining to a single user, i
need to do GET path/to/couch startKey=['foo']&endKey=['foo', 'a']. this
works, but it now means that if i want all messages pertaining to both foo
and bar, i need to run two separate queries.
as i'm writing this, i think i'm starting to see that the problem would be
with having to merge overlapping ranges, but i still would like someone else
to weigh in on this
thanks,
alex.
