ah! so just so I can get cracking on this - Can you be alittle more
specific? e.g
in my component implementation that runs in the request handling after the
normal QueryComponent,
How would I access the specific field value for the documents that were
retrieved?
i.e how would it fit in a code like this if at all:
// docList is the matching documents for given offset/rows/query
DocIterator it = docList.iterator();
while (it.hasNext()) {
docId = it.next();
score = it.score();
// this would've worked if this was stored field:
// reader.document(docId).get(fieldName)
??
}
