did query change in 1.20 ?

[john.tiger]

was there a change from ?key=<some value> what is the right syntax ?

/_design/ddoc/_view/getuserdoc?key="jdoe"

=> "error":"bad_request","reason":"invalid_json"}
so does "key"="jdoe", so does key=jdoe

but
?{key:"jdoe"} returns all doctypes="user" but not just jdoe as wanted

here's the view:

  "views":{
    "getuserdoc":{
      "map":"function(doc) {
        if (doc.doctype == 'user'){
          emit(doc.username, doc);
        }
      }"
    }
