• Performing a fuzzy search may retrieve terms with similar spellings: ((thuat sach) or (bo sach)) ky nang x hoi. hieu ve nham thuc va hanh ((vi cua) OR (di cua)) viet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((thuat sach) OR (bo sach)) ky nang x hoi. hieu ve nham thuc va hanh ((vi cua) OR (di cua)) viet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((thuat sach) or (bo sach)) ky nang x hoi. hieu ve nham thuc va hanh ((vi cua) OR (di cua)) viet*".
