Given a text field ("Vocabulary Indices") of tab-delimited data whose cr lines are organized ascending-numeric first by Column 1 ("Textbook Level" = 1, 2, or 3) then next by Column 2 ("Page Number" = 1 to 200), what are fast ways of retrieving, say, all the cr lines for Textbook Level = 2, Page Number = 54? Thank you. -- Nicolas Cueto
