Reading through Couchdb: The Definitive Guide I came across this section in
chapter 06 :
In the blog app, we use group_level reduce queries to compute the count of
> comments both on a per-post and total basis, achieved by querying the same
> view index with different methods. With some array keys, and assuming each
> key has the value 1:
> ["a","b","c"]
["a","b","e"]
["a","c","m"]
["b","a","c"]
["b","a","g"]
> The reduce view:
> function(keys, values, rereduce) {
return sum(values)
}
> returns the total number of rows between the start and end key. So with
> startkey=["a","b"]&endkey=["b"] (which includes the first 3 of the above
> keys) the result would equal 3.
Earlier in chapter it is stated that:
The startkey and and endkey parameters specify an inclusive range on which
> we can search.
So how come the fourth and fifth rows that satisfy endkey=["b"] condition
are not included in results? I guess I am missing something here. Can
somebody please clarify this for me.
