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