• Performing a fuzzy search may retrieve terms with similar spellings: su sach y nang xa hoi. hieu va ((bac tuc) or (sach duoc)) ((va hanh) OR (va thanh)) tri cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach y nang xa hoi. hieu va ((bac tuc) OR (sach duoc)) ((va hanh) OR (va thanh)) tri cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach y nang xa hoi. hieu va ((bac tuc) or (sach duoc)) ((va hanh) OR (va thanh)) tri cua triet".
• Adding a wildcard symbol may retrieve word variants: su sach y nang xa hoi. hieu va ((bac tuc) or (sach duoc)) ((va hanh) OR (va thanh)) tri cua triet*.
