• Performing a fuzzy search may retrieve terms with similar spellings: thu sach ly quang x ho. hieu ve cam luc va thanh van ((((cua triet) OR (su triet))) or (cau treo))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ly quang x ho. hieu ve cam luc va thanh van ((((cua triet) OR (su triet))) OR (cau treo)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ly quang x ho. hieu ve cam luc va thanh van ((((cua triet) OR (su triet))) or (cau treo))".
• Adding a wildcard symbol may retrieve word variants: thu sach ly quang x ho. hieu ve cam luc va thanh van ((((cua triet) OR (su triet))) or (cau treo))*.
