• If you are trying to use Boolean operators, they must be ALL CAPS: su sac ky trong van hoi. hieu ve coc luc van thanh lap ((((cua tu) OR (cua su))) OR (cua cu)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sac ky trong van hoi. hieu ve coc luc van thanh lap ((((cua tu) OR (cua su))) or (cua cu))".
