• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu xanh - ((hanh mang) OR (hanh san)) ((va trong) OR (va thong)) cong tan thanh cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - ((hanh mang) or (hanh san)) ((va trong) OR (va thong)) cong tan thanh cau~".
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - ((hanh mang) or (hanh san)) ((va trong) OR (va thong)) cong tan thanh cau*.
