• Performing a fuzzy search may retrieve terms with similar spellings: so ((sanh tu) OR (danh tu)) nang ma hoi. thien van cam duc van thanh pho ((dua tren) or (cau tren))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: so ((sanh tu) OR (danh tu)) nang ma hoi. thien van cam duc van thanh pho ((dua tren) OR (cau tren)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "so ((sanh tu) OR (danh tu)) nang ma hoi. thien van cam duc van thanh pho ((dua tren) or (cau tren))".
• Adding a wildcard symbol may retrieve word variants: so ((sanh tu) OR (danh tu)) nang ma hoi. thien van cam duc van thanh pho ((dua tren) or (cau tren))*.
