• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu sach - hanh trinh quan ((((nhung cong) OR (dung cong))) OR (hang nong)) nam tan tap*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sach - hanh trinh quan ((((nhung cong) OR (dung cong))) or (hang nong)) nam tan tap*".
