• If you are trying to use Boolean operators, they must be ALL CAPS: vu sac ky nang van hoi. hieu ve cac luc va ((thanh ca) OR (thanh cac)) ((cua tre) OR (cua te))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sac ky nang van hoi. hieu ve cac luc va ((thanh ca) or (thanh cac)) ((cua tre) OR (cua te))*".
