• Performing a fuzzy search may retrieve terms with similar spellings: ((toc sach) OR (doc sach)) ky lang xa hoi. hieu van cam xuc ((va thanh) or (va tinh)) ban cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((toc sach) OR (doc sach)) ky lang xa hoi. hieu van cam xuc ((va thanh) OR (va tinh)) ban cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((toc sach) OR (doc sach)) ky lang xa hoi. hieu van cam xuc ((va thanh) or (va tinh)) ban cua te*".
