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