• Performing a fuzzy search may retrieve terms with similar spellings: ((tu sach) OR (su sach)) ty sang ma hoa. hieu va cham soc va hanh lai ((cua tre) or (cuu tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (su sach)) ty sang ma hoa. hieu va cham soc va hanh lai ((cua tre) OR (cuu tre))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) OR (su sach)) ty sang ma hoa. hieu va cham soc va hanh lai ((cua tre) or (cuu tre))*".
