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