• If you are trying to use Boolean operators, they must be ALL CAPS: tu san ((ky va) OR (my va)) xay hoi. hieu ve cac xuc ((va hanh) OR (va danh)) vi cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu san ((ky va) or (my va)) xay hoi. hieu ve cac xuc ((va hanh) OR (va danh)) vi cua tre".
