Querying CouchDB documents between a start date and an end date

Question

I\'ve been trying to figure out how to create a CouchDB view that will let me query all the documents that have a start date greater than A and an end date less than B.

Answer 1

Just create a map like this:

function (doc) {emit(doc.timestamp, 1)}

then query the view with:

?descending=true&limit=10&include_docs=true // Get the latest 10 documents

The view will be sorted oldest to latest so descending=true reverses that order.

If you want a specific range.

?startkey="1970-01-01T00:00:00Z"&endkey="1971-01-01T00:00:00Z"

would get you everything in 1970.
