• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((chieu xanh) OR (((hieu lang) OR (nhieu tang)))) - hanh trung cap nhung cong dan toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((chieu xanh) or (((hieu lang) OR (nhieu tang)))) - hanh trung cap nhung cong dan toan cau~".
• Adding a wildcard symbol may retrieve word variants: hoc ((chieu xanh) or (((hieu lang) OR (nhieu tang)))) - hanh trung cap nhung cong dan toan cau*.
