According to my IndexReader's field_infos, all the fields are stored
and indexed, with :with_positions_offsets for the term_vectors.
A look at a term vector for one of these :data fields gives:
#<struct Ferret::Index::TermVector field=:data, terms=[], offsets=nil>
Is this what they look like when you index with :index=>no?
