• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ky trang xa hoi. ((hieu ve) OR (hieu van)) cac xuc ((va danh) or (va thanh)) lai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ky trang xa hoi. ((hieu ve) OR (hieu van)) cac xuc ((va danh) OR (va thanh)) lai cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ky trang xa hoi. ((hieu ve) OR (hieu van)) cac xuc ((va danh) or (va thanh)) lai cua tre".
• Adding a wildcard symbol may retrieve word variants: tu sach ky trang xa hoi. ((hieu ve) OR (hieu van)) cac xuc ((va danh) or (va thanh)) lai cua tre*.
