• Performing a fuzzy search may retrieve terms with similar spellings: ((tu sach) OR (su sach)) ty anh xa hoi. hieu ((ve cau) or (ke cau)) luc nhan hang va ca tren~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (su sach)) ty anh xa hoi. hieu ((ve cau) OR (ke cau)) luc nhan hang va ca tren.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) OR (su sach)) ty anh xa hoi. hieu ((ve cau) or (ke cau)) luc nhan hang va ca tren".
• Adding a wildcard symbol may retrieve word variants: ((tu sach) OR (su sach)) ty anh xa hoi. hieu ((ve cau) or (ke cau)) luc nhan hang va ca tren*.
