• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu sang) OR (chieu xanh)) - thanh ((hung pham) OR (dung cam)) nang cong san hanh lap.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu sang) OR (chieu xanh)) - thanh ((hung pham) or (dung cam)) nang cong san hanh lap".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu sang) OR (chieu xanh)) - thanh ((hung pham) or (dung cam)) nang cong san hanh lap*.
