• Performing a fuzzy search may retrieve terms with similar spellings: ((su sach) OR (so sach)) ty nang x hoi. hieu ve cac xuc va tinh lai ((cua tre) or (cuu tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (so sach)) ty nang x hoi. hieu ve cac xuc va tinh lai ((cua tre) OR (cuu tre)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) OR (so sach)) ty nang x hoi. hieu ve cac xuc va tinh lai ((cua tre) or (cuu tre))".
• Adding a wildcard symbol may retrieve word variants: ((su sach) OR (so sach)) ty nang x hoi. hieu ve cac xuc va tinh lai ((cua tre) or (cuu tre))*.
