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