• If you are trying to use Boolean operators, they must be ALL CAPS: ((hoc thieu) OR (toc thieu)) lang - hanh trinh cua ((thong cong) OR (truong trung)) ban than cap*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc thieu) OR (toc thieu)) lang - hanh trinh cua ((thong cong) or (truong trung)) ban than cap*".
