thanks antony, couchdb is the best thing that happened to our company in the
last one year :)so map is same as emit let me try it, but the map doesnt
work as emit does
emit works to display the documents or rows

*map*
function(doc) { if (doc.appname=="animgifts") emit(doc.name, doc.count); }

*reduce*:
function(keys, values) { return sum(values)}

this outputs properly

but when i try

*map*
function(doc) { if (doc.appname=="animgifts") map(doc.name, doc.count); }

it doesnt output anything with or without reduce function

paul yes i modified the view so it applies to my *doc*
