• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chau tinh) OR (chieu sang)) - ((hanh trang) OR (thanh trung)) cua dong duong dan van ban.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chau tinh) or (chieu sang)) - ((hanh trang) OR (thanh trung)) cua dong duong dan van ban".
