• Performing a fuzzy search may retrieve terms with similar spellings: ((su sach) or (vu sach)) ty nang ma hoi. hieu va cam luc va ((hanh cat) OR (nhanh cay)) cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (vu sach)) ty nang ma hoi. hieu va cam luc va ((hanh cat) OR (nhanh cay)) cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) or (vu sach)) ty nang ma hoi. hieu va cam luc va ((hanh cat) OR (nhanh cay)) cua triet".
