• Performing a fuzzy search may retrieve terms with similar spellings: tu bai ky ((lang van) OR (hoang van)) hoi. hieu ve cham xuc va thanh hai ((cau tren) or (su triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu bai ky ((lang van) OR (hoang van)) hoi. hieu ve cham xuc va thanh hai ((cau tren) OR (su triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu bai ky ((lang van) OR (hoang van)) hoi. hieu ve cham xuc va thanh hai ((cau tren) or (su triet))".
• Adding a wildcard symbol may retrieve word variants: tu bai ky ((lang van) OR (hoang van)) hoi. hieu ve cham xuc va thanh hai ((cau tren) or (su triet))*.
