• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ty nang xa hoi. hieu ((van cham) or (van chat)) soc va danh di ((ca viet) OR (va viet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ty nang xa hoi. hieu ((van cham) OR (van chat)) soc va danh di ((ca viet) OR (va viet))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ty nang xa hoi. hieu ((van cham) or (van chat)) soc va danh di ((ca viet) OR (va viet))*".
