• If you are trying to use Boolean operators, they must be ALL CAPS: theo chua xang - ((hanh tang) OR (hanh mang)) ((luan tong) OR (quan dong)) thong va toan cau~.
• Adding a wildcard symbol may retrieve word variants: theo chua xang - ((hanh tang) or (hanh mang)) ((luan tong) or (quan dong)) thong va toan cau*.
