• Performing a fuzzy search may retrieve terms with similar spellings: ((tu sach) OR (su sach)) thi hanh xa hoi. hieu ve cac xuc ((ban thanh) or (ban hang)) hai cua viet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (su sach)) thi hanh xa hoi. hieu ve cac xuc ((ban thanh) OR (ban hang)) hai cua viet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) OR (su sach)) thi hanh xa hoi. hieu ve cac xuc ((ban thanh) or (ban hang)) hai cua viet*".
