• Performing a fuzzy search may retrieve terms with similar spellings: ((vu sach) OR (su sach)) ly nang ((ma hoi) or (xa hoi)). lieu va cam thuc va lanh hai cau treo~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((vu sach) OR (su sach)) ly nang ((ma hoi) OR (xa hoi)). lieu va cam thuc va lanh hai cau treo.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((vu sach) OR (su sach)) ly nang ((ma hoi) or (xa hoi)). lieu va cam thuc va lanh hai cau treo".
• Adding a wildcard symbol may retrieve word variants: ((vu sach) OR (su sach)) ly nang ((ma hoi) or (xa hoi)). lieu va cam thuc va lanh hai cau treo*.
