...a page's worth of byte count, but this fix looks accurate to me. It's better for maintenance, too, because the function never intends to migrate "some number of bytes". It intends to migrate exactly one page. Hope I'm not missing something fundamental, but: Reviewed-by: John Hubbard <jhubbard at nvidia.com thanks, -- John Hubbard NVIDIA

Hi, I tried opening a new ticket with a patch I wanted to submit. But when I tried to attach files to the ticket I keep getting a ticket not found error. I kept trying to get it to work, but I accidentally opened 4 new tickets. Sorry. Charlie -- Posted via http://www.ruby-forum.com/.

I''m trying to add a way to query across associations for a model in acts_as_ferret. Say I have a model A and it has a relationship with model B. Like say a Book has many pages. I want to search across the pages of the Book and produce a list of unique books who''s pages match the terms. So if I have a page that hits then I will add that book to my list of results. Right

I have a problem, and I think it''s because stop word analysis isn''t happenning in the queries. I think it''s the way ferret is doing things that''s causing this bug.
