• Performing a fuzzy search may retrieve terms with similar spellings: te san ky ((tang ma) OR (mang may)) hoi. hieu va cam xuc va thanh vi ((cau tren) or (ca tren))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te san ky ((tang ma) OR (mang may)) hoi. hieu va cam xuc va thanh vi ((cau tren) OR (ca tren)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te san ky ((tang ma) OR (mang may)) hoi. hieu va cam xuc va thanh vi ((cau tren) or (ca tren))".
• Adding a wildcard symbol may retrieve word variants: te san ky ((tang ma) OR (mang may)) hoi. hieu va cam xuc va thanh vi ((cau tren) or (ca tren))*.
