• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ty ((lang van) or (hoang van)) hoi. hieu ((van cam) OR (van lam)) phuc may tinh va va viet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ty ((lang van) OR (hoang van)) hoi. hieu ((van cam) OR (van lam)) phuc may tinh va va viet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ty ((lang van) or (hoang van)) hoi. hieu ((van cam) OR (van lam)) phuc may tinh va va viet".
• Adding a wildcard symbol may retrieve word variants: tu sach ty ((lang van) or (hoang van)) hoi. hieu ((van cam) OR (van lam)) phuc may tinh va va viet*.
