• Performing a fuzzy search may retrieve terms with similar spellings: te ((sach ky) OR (sac ky)) nang xa hoi. hieu ((va cao) or (vu cham)) thuc va danh di cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach ky) OR (sac ky)) nang xa hoi. hieu ((va cao) OR (vu cham)) thuc va danh di cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach ky) OR (sac ky)) nang xa hoi. hieu ((va cao) or (vu cham)) thuc va danh di cua triet".
• Adding a wildcard symbol may retrieve word variants: te ((sach ky) OR (sac ky)) nang xa hoi. hieu ((va cao) or (vu cham)) thuc va danh di cua triet*.
