• Performing a fuzzy search may retrieve terms with similar spellings: su sach ty nang ma hoi. ((hieu ve) OR (hieu va)) cham xuc ((va danh) or (va dan)) vai cau treo~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ty nang ma hoi. ((hieu ve) OR (hieu va)) cham xuc ((va danh) OR (va dan)) vai cau treo*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ty nang ma hoi. ((hieu ve) OR (hieu va)) cham xuc ((va danh) or (va dan)) vai cau treo*".
