Thanks, I understand that better now... (I hope).
It looks like the best way to do this would be to extract the filename from
the path just after the code snippet below:
public static Document Document(File f)
throws IOException, InterruptedException {
// make a new, empty document
Document doc = new Document();
// Add the url as a field named "path". Use a field that is
// indexed (i.e. searchable), but don't tokenize the field into words.
doc.add(new Field("path", f.getPath().replace(dirSep, '/'),
Field.Store.YES,
Field.Index.UN_TOKENIZED));
This way the filename is available for all the subsequent if {} blocks.
