• Performing a fuzzy search may retrieve terms with similar spellings: tu sach thieu lang xa hoi. hieu ((ve cac) OR (vien cac)) duc gia hanh ((vi cau) or (da cau)) treo~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach thieu lang xa hoi. hieu ((ve cac) OR (vien cac)) duc gia hanh ((vi cau) OR (da cau)) treo.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach thieu lang xa hoi. hieu ((ve cac) OR (vien cac)) duc gia hanh ((vi cau) or (da cau)) treo".
• Adding a wildcard symbol may retrieve word variants: tu sach thieu lang xa hoi. hieu ((ve cac) OR (vien cac)) duc gia hanh ((vi cau) or (da cau)) treo*.
