• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((tiem nang) OR (tin nang)) - hanh trong van nhung cong ((san toan) OR (van toan)) cao.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((tiem nang) OR (tin nang)) - hanh trong van nhung cong ((san toan) or (van toan)) cao".
• Adding a wildcard symbol may retrieve word variants: theo ((tiem nang) OR (tin nang)) - hanh trong van nhung cong ((san toan) or (van toan)) cao*.
