• Performing a fuzzy search may retrieve terms with similar spellings: su sac ky hang ((tai hoi) OR (dai hoi)). hieu vu cham luc va tinh loi ((cua tre) or (cua te))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sac ky hang ((tai hoi) OR (dai hoi)). hieu vu cham luc va tinh loi ((cua tre) OR (cua te))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sac ky hang ((tai hoi) OR (dai hoi)). hieu vu cham luc va tinh loi ((cua tre) or (cua te))*".
