• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu sach - nhanh thanh va nhung ((((cong van) OR (cong tan))) OR (cong san)) tuan cao*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sach - nhanh thanh va nhung ((((cong van) OR (cong tan))) or (cong san)) tuan cao*".
