• Performing a fuzzy search may retrieve terms with similar spellings: te sach ((tu nang) or (tu nano)) x hoi. hieu ((va cao) OR (va co)) tuc va thanh vinh cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((tu nang) OR (tu nano)) x hoi. hieu ((va cao) OR (va co)) tuc va thanh vinh cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((tu nang) or (tu nano)) x hoi. hieu ((va cao) OR (va co)) tuc va thanh vinh cuu tre".
• Adding a wildcard symbol may retrieve word variants: te sach ((tu nang) or (tu nano)) x hoi. hieu ((va cao) OR (va co)) tuc va thanh vinh cuu tre*.
