• If you are trying to use Boolean operators, they must be ALL CAPS: hoc thieu sach - hanh truong thpt ((((nhung cong) OR (nhung don))) OR (hang cong)) van tan ban.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu sach - hanh truong thpt ((((nhung cong) OR (nhung don))) or (hang cong)) van tan ban".
