• If you are trying to use Boolean operators, they must be ALL CAPS: hoc trieu tinh - ((hanh tang) OR (((hanh mang) OR (hanh trang)))) cua tong thuong dan than ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc trieu tinh - ((hanh tang) or (((hanh mang) OR (hanh trang)))) cua tong thuong dan than ban~".
• Adding a wildcard symbol may retrieve word variants: hoc trieu tinh - ((hanh tang) or (((hanh mang) OR (hanh trang)))) cua tong thuong dan than ban*.
