Hi
CouchDB takes care of the view slicing for you (see http://wiki.apache.org/couchdb/HTTP_view_API
. You'd write a view that emits some key:values, and then do the query
you describe (?key=foo) to return only the values with key = foo. You
can also do startkey=foo and endkey=bar to get a slice of the view
(e.g. look for continuous data in a range). You don't need to worry
about this in writing your view, since the view is generated for all
keys.
Cheers

Hello,
use case:
- change the value of a field of documents
question:
is there a way to pass a request parameter to the view ?
I would imagine some like this:
/db/view?key=value
then in the view function (doc) {
if (doc match some criteria)
doc.Type = value;
}
in the reduce function, I can then return the # of changed
documents....
But the view function only accepts one argument 'doc'.
Do I have to get a list, then get each document, then put ? does not
seem to be efficient.
rgds,
