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