• Performing a fuzzy search may retrieve terms with similar spellings: ho ((hieu van) or (chieu sang)) - hanh tang lan phuong huong van ((toan cau) OR (toan cao))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((hieu van) OR (chieu sang)) - hanh tang lan phuong huong van ((toan cau) OR (toan cao))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((hieu van) or (chieu sang)) - hanh tang lan phuong huong van ((toan cau) OR (toan cao))*".
