IndexWriter.updateDocument(Term term, Document doc [,Analyzer a])
could simplify this to:
  - create updated document from the db
  - writer.updateDocument(idField, updatedDocument)

But regarding the original question, here still update==remove+add, ie no
"append/update-in-place" logic is supported (or planned).
