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