• Performing a fuzzy search may retrieve terms with similar spellings: tu cac ky sang ma hoi. hieu ve cao suc va thanh vai ((cuu tre) or (((cua tre) OR (dua tren))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu cac ky sang ma hoi. hieu ve cao suc va thanh vai ((cuu tre) OR (((cua tre) OR (dua tren)))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu cac ky sang ma hoi. hieu ve cao suc va thanh vai ((cuu tre) or (((cua tre) OR (dua tren))))".
• Adding a wildcard symbol may retrieve word variants: tu cac ky sang ma hoi. hieu ve cao suc va thanh vai ((cuu tre) or (((cua tre) OR (dua tren))))*.
