• Performing a fuzzy search may retrieve terms with similar spellings: su sac ky ((nang ma) OR (nang cao)) hoi. hieu ve cam tuc va ((thanh vi) or (thanh va)) hoa viet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sac ky ((nang ma) OR (nang cao)) hoi. hieu ve cam tuc va ((thanh vi) OR (thanh va)) hoa viet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sac ky ((nang ma) OR (nang cao)) hoi. hieu ve cam tuc va ((thanh vi) or (thanh va)) hoa viet*".
