Hi,
thanks for testing this out, this looks like a configuration issue,
_multi should be a registered httpd_db_handler in local.ini as
follows.
[httpd_db_handlers]
_multi = {multiview_httpd, handle_request}
I will look into this and make sure it gets added.
In the test scripts the following code
var ddocThree = {
_id:"_design/three",
views: {
"test" : {map: "function (doc) {if (doc.integer % 3 == 0)
emit(doc.integer, null)};"}
}
};
is emitting keys with the doc._id as an integer, in this case for
multiples of 3, the second view ddocFour is emitting the documents
with keys that are multiples of 4.
Hence when we do a multiview and find the intersections of these two
views we get the documents whose id (as integer keys) are multiples of
12.
