// The map function is the most critical part of any view as it provides the
// logical mapping between the input fields of the individual objects stored
// within Couchbase to the information output when the view is accessed.
//
// Read more about how to write map functions at:
// http://www.couchbase.com/docs/couchbase-manual-2.0/couchbase-views-writing-map.html
function(doc, meta) {
emit(meta.id, null);
}
// You can also check out following examples
//
// The simplest example of a map function:
//
// function(doc, meta) {
// emit(meta.id, doc);
// }
//
// Slightly more complex example of a function that defines a view on values
// computed from customer documents:
//
// function(doc, meta) {
// if (doc.type == "customer") {
// emit(meta.id, {last_name: doc.last_name, first_name: doc.first_name});
// }
// }
//
// To be able to filter or sort the view by some document property, you
// would use that property for the key. For example, the following view
// would allow you to lookup customer documents by the last_name or
// first_name fields (your keys could be compound, e.g. arrays):
//
// function(doc, meta) {
// if (doc.type == "customer") {
// emit(doc.last_name, {first_name: doc.first_name});
// emit(doc.first_name, {last_name: doc.last_name});
// }
// }
