Subject RE: Field Question

John,

Thanks for answering. 
So if I have a document "A "with field "foo" and the field has attribute
Field.NO and
I have document "B" with field "foo" and the field is Field.TOKENIZED.
Will IndexReader.getFieldNames(IndexReader.FieldOption.INDEXED) return field
"foo"?

Thanks,

Dimitri
