• Performing a fuzzy search may retrieve terms with similar spellings: ho chieu sach - hanh mang ca thuong ((((con tap) OR (cong tan))) or (cong tac)) quan cap~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu sach - hanh mang ca thuong ((((con tap) OR (cong tan))) OR (cong tac)) quan cap*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sach - hanh mang ca thuong ((((con tap) OR (cong tan))) or (cong tac)) quan cap*".
