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