• Performing a fuzzy search may retrieve terms with similar spellings: (( tu sach ((ca ve) OR (va ve)) giai hoan hoang minh ) or ( thu sach cap vi giai phong khong tin ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( tu sach ((ca ve) OR (va ve)) giai hoan hoang minh ) OR ( thu sach cap vi giai phong khong tin )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( tu sach ((ca ve) OR (va ve)) giai hoan hoang minh ) or ( thu sach cap vi giai phong khong tin ))".
• Adding a wildcard symbol may retrieve word variants: (( tu sach ((ca ve) OR (va ve)) giai hoan hoang minh ) or ( thu sach cap vi giai phong khong tin ))*.
