• If you are trying to use Boolean operators, they must be ALL CAPS: doi ((chieu xanh) OR (chieu sang)) - hanh manh cua thong cong san ((tran cao) OR (trang o))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi ((chieu xanh) OR (chieu sang)) - hanh manh cua thong cong san ((tran cao) or (trang o))~".
• Adding a wildcard symbol may retrieve word variants: doi ((chieu xanh) OR (chieu sang)) - hanh manh cua thong cong san ((tran cao) or (trang o))*.
