• If you are trying to use Boolean operators, they must be ALL CAPS: ((hoc thieu) OR (toc thieu)) xanh - thanh trung cua khong ((nang sang) OR (nong san)) gian cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc thieu) OR (toc thieu)) xanh - thanh trung cua khong ((nang sang) or (nong san)) gian cau".
• Adding a wildcard symbol may retrieve word variants: ((hoc thieu) OR (toc thieu)) xanh - thanh trung cua khong ((nang sang) or (nong san)) gian cau*.
