• If you are trying to use Boolean operators, they must be ALL CAPS: ((thi chien) OR (theo chieu)) xanh - hanh tang va ((duong vuong) OR (duong trong)) anh toan cao.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((thi chien) or (theo chieu)) xanh - hanh tang va ((duong vuong) OR (duong trong)) anh toan cao".
• Adding a wildcard symbol may retrieve word variants: ((thi chien) or (theo chieu)) xanh - hanh tang va ((duong vuong) OR (duong trong)) anh toan cao*.
