• Performing a fuzzy search may retrieve terms with similar spellings: so ((sach thu) or (sach thue)) hang ma hoi. hieu ve pham chuc va danh vai ((cua te) OR (cua tu))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: so ((sach thu) OR (sach thue)) hang ma hoi. hieu ve pham chuc va danh vai ((cua te) OR (cua tu)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "so ((sach thu) or (sach thue)) hang ma hoi. hieu ve pham chuc va danh vai ((cua te) OR (cua tu))".
• Adding a wildcard symbol may retrieve word variants: so ((sach thu) or (sach thue)) hang ma hoi. hieu ve pham chuc va danh vai ((cua te) OR (cua tu))*.
