• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ly hang ((ma hoi) or (mai hoi)). hieu ve cam ((xuc va) OR (luc va)) hanh di cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ly hang ((ma hoi) OR (mai hoi)). hieu ve cam ((xuc va) OR (luc va)) hanh di cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ly hang ((ma hoi) or (mai hoi)). hieu ve cam ((xuc va) OR (luc va)) hanh di cua te*".
