• Performing a fuzzy search may retrieve terms with similar spellings: su sach thu lang xa hoi. hieu va ((cac duc) or (cao duc)) ((va danh) OR (va dan)) vai cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach thu lang xa hoi. hieu va ((cac duc) OR (cao duc)) ((va danh) OR (va dan)) vai cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach thu lang xa hoi. hieu va ((cac duc) or (cao duc)) ((va danh) OR (va dan)) vai cua te*".
