This just means couchdb-lucene has encountered a document that doesn't
have a "headers" element. In general you should add guard clauses
anyway;
function(doc) {
if (doc.headers && doc.headers.core && doc.headers.core.user) {
var res = new Document();
res.add( doc.headers.core.user );
return res;
}
return null;
}
