• Performing a fuzzy search may retrieve terms with similar spellings: doi chiu trach - ((hanh tang) OR (anh tang)) cua dung cong tap ((toan cau) or (toan ban))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: doi chiu trach - ((hanh tang) OR (anh tang)) cua dung cong tap ((toan cau) OR (toan ban))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chiu trach - ((hanh tang) OR (anh tang)) cua dung cong tap ((toan cau) or (toan ban))*".
