• Performing a fuzzy search may retrieve terms with similar spellings: su sach ki nang o hoi. hieu ((ve cam) OR (ve cham)) tuc xa hanh vai ((va triet) or (su triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ki nang o hoi. hieu ((ve cam) OR (ve cham)) tuc xa hanh vai ((va triet) OR (su triet))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ki nang o hoi. hieu ((ve cam) OR (ve cham)) tuc xa hanh vai ((va triet) or (su triet))*".
