• Performing a fuzzy search may retrieve terms with similar spellings: ((tu sach) OR (su sach)) ty lang xa hoi. hieu van cam ((xuc may) or (xuc hay)) tinh va va viet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (su sach)) ty lang xa hoi. hieu van cam ((xuc may) OR (xuc hay)) tinh va va viet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) OR (su sach)) ty lang xa hoi. hieu van cam ((xuc may) or (xuc hay)) tinh va va viet".
• Adding a wildcard symbol may retrieve word variants: ((tu sach) OR (su sach)) ty lang xa hoi. hieu van cam ((xuc may) or (xuc hay)) tinh va va viet*.
