• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu sang - ((hanh trung) OR (thanh trung)) dap ung cong dan ((toan cau) OR (toan ban)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sang - ((hanh trung) or (thanh trung)) dap ung cong dan ((toan cau) OR (toan ban))".
