• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ky ((tang lai) OR (tang loi)) hoi. hieu su chao xu va thanh vai ((cua tu) or (cua su))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ky ((tang lai) OR (tang loi)) hoi. hieu su chao xu va thanh vai ((cua tu) OR (cua su)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ky ((tang lai) OR (tang loi)) hoi. hieu su chao xu va thanh vai ((cua tu) or (cua su))".
• Adding a wildcard symbol may retrieve word variants: tu sach ky ((tang lai) OR (tang loi)) hoi. hieu su chao xu va thanh vai ((cua tu) or (cua su))*.
