• Performing a fuzzy search may retrieve terms with similar spellings: ((so sach) or (do sanh)) ky van xay hoi. hieu ((van cham) OR (va cham)) tuc van anh vai cua viet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((so sach) OR (do sanh)) ky van xay hoi. hieu ((van cham) OR (va cham)) tuc van anh vai cua viet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((so sach) or (do sanh)) ky van xay hoi. hieu ((van cham) OR (va cham)) tuc van anh vai cua viet*".
