Using filters
I am going through many of the tutorials for design docs, and trying various things.
I saw that filters are used in replication, but it is correct that a "filter" cannot get accessed via a URL, like other handlers?
Given the design doc filter below:
{
"_id": "_design/showme",
"_rev": "9-8d74f29a2890e402275a54f5b17997fd",
"filters": {
"useit": "function(doc, req){...}"
}
}
(yes there is really a function provided, edited for content)
And attempting to run the filter using this:
http://localhost:5984/db/_design/showme/_filter/useit
Returns the following:
{"error":"not_found","reason":"missing handler: _filter"}
This URL structure works for shows, views, lists which are all accessed through this "handler". Why the difference?
