• If you are trying to use Boolean operators, they must be ALL CAPS: ((theo chua) OR (theo chu)) tinh - hanh ((hang ca) OR (tang cua)) nhung xuong dan toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((theo chua) OR (theo chu)) tinh - hanh ((hang ca) or (tang cua)) nhung xuong dan toan cau~".
• Adding a wildcard symbol may retrieve word variants: ((theo chua) OR (theo chu)) tinh - hanh ((hang ca) or (tang cua)) nhung xuong dan toan cau*.
