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