• If you are trying to use Boolean operators, they must be ALL CAPS: doi ((chieu xanh) OR (((chieu sang) OR (chieu sach)))) - thanh trong van dung trong van thanh tai~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi ((chieu xanh) or (((chieu sang) OR (chieu sach)))) - thanh trong van dung trong van thanh tai~".
• Adding a wildcard symbol may retrieve word variants: doi ((chieu xanh) or (((chieu sang) OR (chieu sach)))) - thanh trong van dung trong van thanh tai*.
