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