• Performing a fuzzy search may retrieve terms with similar spellings: ((tu sach) or (thu sach)) y nang mai khoi. hieu ve cham xuc van hanh vi ((cua nuoc) OR (cua thuoc))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (thu sach)) y nang mai khoi. hieu ve cham xuc van hanh vi ((cua nuoc) OR (cua thuoc)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) or (thu sach)) y nang mai khoi. hieu ve cham xuc van hanh vi ((cua nuoc) OR (cua thuoc))".
• Adding a wildcard symbol may retrieve word variants: ((tu sach) or (thu sach)) y nang mai khoi. hieu ve cham xuc van hanh vi ((cua nuoc) OR (cua thuoc))*.
