• Performing a fuzzy search may retrieve terms with similar spellings: ((su sach) or (thu sach)) ty nang xa hoi. thien ((van hac) OR (van ha)) tuc gia thanh lap cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (thu sach)) ty nang xa hoi. thien ((van hac) OR (van ha)) tuc gia thanh lap cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) or (thu sach)) ty nang xa hoi. thien ((van hac) OR (van ha)) tuc gia thanh lap cua triet".
• Adding a wildcard symbol may retrieve word variants: ((su sach) or (thu sach)) ty nang xa hoi. thien ((van hac) OR (van ha)) tuc gia thanh lap cua triet*.
