• Performing a fuzzy search may retrieve terms with similar spellings: theo chu sach - hanh ((((trung cua) OR (trung cap))) or (tang cua)) nhung cong dan toan cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: theo chu sach - hanh ((((trung cua) OR (trung cap))) OR (tang cua)) nhung cong dan toan cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chu sach - hanh ((((trung cua) OR (trung cap))) or (tang cua)) nhung cong dan toan cau*".
