CouchDB View - Filter by List Field Attribute (doc.objects.[0].attribute) -

i need create view lists values attribute of doc field.

sample doc:

{    "_id": "003e5a9742e04ce7a6791aa845405c17",    "title", "testdoc",    "samples": [        {            "confidence": "high",            "handle": "joetest"        }    ] } 

example using doc, want view return values "handle"

i found example heading - contents of object specific attributes e.g. doc.objects.[0].attribute. when fill in attribute name, e.g. "handle" , replace doc.objects doc.samples, no results:

toggle line numbers // map function(doc) {   (var idx in doc.objects) {     emit(doc.objects[idx], attribute)   } } 

that create array of key-value-pairs key alway value of handle. replace null value want e.g. doc.title. if want doc attached every row use query parameter ?include_docs=true while requesting view.

// map function (doc) {   var samples = doc.samples   for(var = 0, sample; sample = samples[i++];) {     emit(sample.handle, null)   } }
