• Performing a fuzzy search may retrieve terms with similar spellings: te sach tu sang dai hoi. ((((hieu va) OR (lieu va))) or (thi van)) cam xuc va nang hai van triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach tu sang dai hoi. ((((hieu va) OR (lieu va))) OR (thi van)) cam xuc va nang hai van triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach tu sang dai hoi. ((((hieu va) OR (lieu va))) or (thi van)) cam xuc va nang hai van triet".
• Adding a wildcard symbol may retrieve word variants: te sach tu sang dai hoi. ((((hieu va) OR (lieu va))) or (thi van)) cam xuc va nang hai van triet*.
