• If you are trying to use Boolean operators, they must be ALL CAPS: ((thi chieu) OR (theo tieu)) tinh - hang ((hang cua) OR (mang cua)) cong thuong va than cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((thi chieu) or (theo tieu)) tinh - hang ((hang cua) OR (mang cua)) cong thuong va than cao~".
• Adding a wildcard symbol may retrieve word variants: ((thi chieu) or (theo tieu)) tinh - hang ((hang cua) OR (mang cua)) cong thuong va than cao*.
