• Performing a fuzzy search may retrieve terms with similar spellings: su sac ky ((mang may) or (tang ma)) hoi. hieu ve nhan luc va danh va ((su triet) OR (su viet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sac ky ((mang may) OR (tang ma)) hoi. hieu ve nhan luc va danh va ((su triet) OR (su viet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sac ky ((mang may) or (tang ma)) hoi. hieu ve nhan luc va danh va ((su triet) OR (su viet))".
• Adding a wildcard symbol may retrieve word variants: su sac ky ((mang may) or (tang ma)) hoi. hieu ve nhan luc va danh va ((su triet) OR (su viet))*.
