• Performing a fuzzy search may retrieve terms with similar spellings: tu sach _ sang mai hoi. hieu ve cham xuc va dan lai ((((dung tren) OR (dung trung))) or (cua te))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach _ sang mai hoi. hieu ve cham xuc va dan lai ((((dung tren) OR (dung trung))) OR (cua te)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach _ sang mai hoi. hieu ve cham xuc va dan lai ((((dung tren) OR (dung trung))) or (cua te))".
• Adding a wildcard symbol may retrieve word variants: tu sach _ sang mai hoi. hieu ve cham xuc va dan lai ((((dung tren) OR (dung trung))) or (cua te))*.
