• Performing a fuzzy search may retrieve terms with similar spellings: te sach ty ((dang van) OR (hang va)) hoa. hieu ve cam ((xuc va) or (duc va)) thinh le va triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ty ((dang van) OR (hang va)) hoa. hieu ve cam ((xuc va) OR (duc va)) thinh le va triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ty ((dang van) OR (hang va)) hoa. hieu ve cam ((xuc va) or (duc va)) thinh le va triet*".
