• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((((chieu khong) OR (chien chong))) OR (thieu quang)) - canh tranh cua trong cong dan hang va*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((((chieu khong) OR (chien chong))) or (thieu quang)) - canh tranh cua trong cong dan hang va*".
