• Performing a fuzzy search may retrieve terms with similar spellings: su sach ty ((lang xa) OR (lang ha)) hoi. lieu va cham xuc ban hanh vi ((dua tren) or (cua tuc))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ty ((lang xa) OR (lang ha)) hoi. lieu va cham xuc ban hanh vi ((dua tren) OR (cua tuc)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ty ((lang xa) OR (lang ha)) hoi. lieu va cham xuc ban hanh vi ((dua tren) or (cua tuc))".
• Adding a wildcard symbol may retrieve word variants: su sach ty ((lang xa) OR (lang ha)) hoi. lieu va cham xuc ban hanh vi ((dua tren) or (cua tuc))*.
