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