• Performing a fuzzy search may retrieve terms with similar spellings: thuat sach ky ((lang xa) or (dang van)) hoi. hieu van chau phu va danh di ((cua tre) OR (cua te))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thuat sach ky ((lang xa) OR (dang van)) hoi. hieu van chau phu va danh di ((cua tre) OR (cua te)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat sach ky ((lang xa) or (dang van)) hoi. hieu van chau phu va danh di ((cua tre) OR (cua te))".
• Adding a wildcard symbol may retrieve word variants: thuat sach ky ((lang xa) or (dang van)) hoi. hieu van chau phu va danh di ((cua tre) OR (cua te))*.
