Hi, Im new to couchDB and im curious what couchDB behaves when I try to MAPPING non-existing fields. For example: Document 1 has field1, field2, field3 Document 2 has field1, fied4, field5 function1 (doc) { emit (doc.field1, doc.field4); } function2 (doc) { emit (doc.field6, doc.field7); } What are the results from function 1 and function 2 ? Thanks.
