• If you are trying to use Boolean operators, they must be ALL CAPS: te sac ky ((dang xa) OR (dang xay)) hoi. thien van nam xuc ((va dinh) OR (va kinh)) va cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sac ky ((dang xa) OR (dang xay)) hoi. thien van nam xuc ((va dinh) or (va kinh)) va cua tre".
