• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ty tang ma hoi. ((chieu tu) OR (chu tu)) cham duc va hanh lam ((cua tre) OR (cua te))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ty tang ma hoi. ((chieu tu) OR (chu tu)) cham duc va hanh lam ((cua tre) or (cua te))*".
