Nomatter what if you are going to update a document, you will have to
open a writer for doing so (or, use a writer you already have open).

The Term that you pass as the first argument to updateDocument must
"identify" the document you want to replace. EG you could add a field
"documentID" that has a unique value per document. You then pass in
Term("documentID", <string-ID>) to updateDocument. In your case maybe
you could use a canonical fileName or URI to identify the document.
Then, you put your modified source as a Field into the second argument
(document) to the updateDocument method.
