Subject [jira] [Commented] (COUCHDB-1228) Key range error apparently ignores view collation
Date Sat, 06 Aug 2011 16:04:27 GMT

Paul Joseph Davis commented on COUCHDB-1228:
--------------------------------------------

@Bob

Quite right. Though that code will have to poke into the design doc to handle that warning
case. I'm not sure what _all_docs has to do with it. It only uses raw collation.

> I have created a view (no reduce function) with "options":{"collation":"raw"} and emit
documents with keys "A", "C" and "b". Running a request on that view with no parameters, I
get as expected all three documents in order "A", "C" and "b" as required by the raw collation
(instead of "A", "b", "C" for the default ICU collation).
> However, when I run a request with start key "B" and end key "a", I expect the "C" document
to be returned alone (as "B" < "C" < "a") but couchDB responds:
> { "error": "query_parse_error", "reason": "No rows can match your key range, reverse
your start_key and end_key or set descending=true" }
> This error would make sense if I had been using the default ICU collation, where "B"
> "a", but with the raw collation the reverse ("B" > "a") is true. It looks as if the
key order warning does not take the view collation into account.
