• Performing a fuzzy search may retrieve terms with similar spellings: ((su sach) or (so sach)) kho trang xa hoi. hieu ((van am) OR (van lam)) thuc tat thanh vi cua viet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (so sach)) kho trang xa hoi. hieu ((van am) OR (van lam)) thuc tat thanh vi cua viet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) or (so sach)) kho trang xa hoi. hieu ((van am) OR (van lam)) thuc tat thanh vi cua viet".
• Adding a wildcard symbol may retrieve word variants: ((su sach) or (so sach)) kho trang xa hoi. hieu ((van am) OR (van lam)) thuc tat thanh vi cua viet*.
