• Performing a fuzzy search may retrieve terms with similar spellings: theo tieu xanh - canh ((((tranh va) OR (trinh va))) or (trinh quan)) nhung duong van phan cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: theo tieu xanh - canh ((((tranh va) OR (trinh va))) OR (trinh quan)) nhung duong van phan cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo tieu xanh - canh ((((tranh va) OR (trinh va))) or (trinh quan)) nhung duong van phan cau".
• Adding a wildcard symbol may retrieve word variants: theo tieu xanh - canh ((((tranh va) OR (trinh va))) or (trinh quan)) nhung duong van phan cau*.
