• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu tinh) OR (chieu sang)) - thanh trung khanh dung trong ((ban phan) OR (ban than)) cac.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu tinh) or (chieu sang)) - thanh trung khanh dung trong ((ban phan) OR (ban than)) cac".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu tinh) or (chieu sang)) - thanh trung khanh dung trong ((ban phan) OR (ban than)) cac*.
