• Performing a fuzzy search may retrieve terms with similar spellings: te sach y ((nang o) or (nang ho)) hoi. ((hieu cu) OR (hieu su)) nhan luc va danh dai cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y ((nang o) OR (nang ho)) hoi. ((hieu cu) OR (hieu su)) nhan luc va danh dai cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y ((nang o) or (nang ho)) hoi. ((hieu cu) OR (hieu su)) nhan luc va danh dai cua triet".
• Adding a wildcard symbol may retrieve word variants: te sach y ((nang o) or (nang ho)) hoi. ((hieu cu) OR (hieu su)) nhan luc va danh dai cua triet*.
