• If you are trying to use Boolean operators, they must be ALL CAPS: hoc thieu sach - thanh tung cua ((nhung cong) OR (((hang cong) OR (hang nong)))) ban than cao*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu sach - thanh tung cua ((nhung cong) or (((hang cong) OR (hang nong)))) ban than cao*".
