• Performing a fuzzy search may retrieve terms with similar spellings: thu sach ty lang ((van hoi) OR (van hoc)). hieu vu cham xuc van thanh vi ((cu tren) or (dat tren))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ty lang ((van hoi) OR (van hoc)). hieu vu cham xuc van thanh vi ((cu tren) OR (dat tren))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ty lang ((van hoi) OR (van hoc)). hieu vu cham xuc van thanh vi ((cu tren) or (dat tren))*".
