• Performing a fuzzy search may retrieve terms with similar spellings: thu sach ty lang van hoe. hieu ve cam duc va ((hang tai) or (thang tai)) ((cau treo) OR (cau theo))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ty lang van hoe. hieu ve cam duc va ((hang tai) OR (thang tai)) ((cau treo) OR (cau theo)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ty lang van hoe. hieu ve cam duc va ((hang tai) or (thang tai)) ((cau treo) OR (cau theo))".
• Adding a wildcard symbol may retrieve word variants: thu sach ty lang van hoe. hieu ve cam duc va ((hang tai) or (thang tai)) ((cau treo) OR (cau theo))*.
