Additionally (and I haven't been in low-level Lucene for a LONG time
so caveat emptor), in general ID types should not be tokenized. I'd
model my field definition after the Lucene StringField class. It looks like
you can avoid defining a FieldType altogether and just use
StringField.TYPE_STORED for your iDoc.add call....
FWIW,
