• Performing a fuzzy search may retrieve terms with similar spellings: tu sach thu lang ha hoi. thi van cam ((xuc va) or (thuc day)) hanh lai ((cua tre) OR (cua triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach thu lang ha hoi. thi van cam ((xuc va) OR (thuc day)) hanh lai ((cua tre) OR (cua triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach thu lang ha hoi. thi van cam ((xuc va) or (thuc day)) hanh lai ((cua tre) OR (cua triet))".
• Adding a wildcard symbol may retrieve word variants: tu sach thu lang ha hoi. thi van cam ((xuc va) or (thuc day)) hanh lai ((cua tre) OR (cua triet))*.
