Very similar to these two CouchDB questions: 3311225 and 8924793, except that these approaches don't allow partial matching. Having e.g. these entries:
[{_id: 1, status: 'NEW', name: 'a'},
{_id: 2, status: 'NEW', name: 'aab'},
{_id: 3, status: 'NEW', name: 'ab'},
{_id: 4, status: 'NEW', name: 'aaa'},
{_id: 5, status: 'NEW', name: 'aa'}]
and key
[status, name, _id]
There seems to be no way to
- filter these entries by status (full string match) and name (partial string match ~
startsWith
) - order them by id
- paginate them
because of the partial string match on name. The high value unicode character \uffff that allows this partial match also causes to ignore the _id
part of the key, meaning the resulting entries are not sorted by _id
, but rather by status and name.
var status = 'NEW';
var name = 'aa'
var query = {
startkey: [status, name],
endkey: [status, name + '\uffff', {}],
skip: 0,
limit: 10
};
results in
[{_id: 5, status: 'NEW', name: 'aa'},
{_id: 4, status: 'NEW', name: 'aaa'},
{_id: 2, status: 'NEW', name: 'aab'}]
There is no option to sort in memory, as this would only sort the individual pages, and not the entire data set. Any ideas about this?
