• Performing a fuzzy search may retrieve terms with similar spellings: tu sach thu lang xa hoi. ((hieu ve) OR (hieu va)) cham xuc ((va tinh) or (ban hanh)) vai cau tren~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach thu lang xa hoi. ((hieu ve) OR (hieu va)) cham xuc ((va tinh) OR (ban hanh)) vai cau tren*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach thu lang xa hoi. ((hieu ve) OR (hieu va)) cham xuc ((va tinh) or (ban hanh)) vai cau tren*".
