• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho chieu) OR (doi chieu)) xanh - ((hanh tang) OR (hanh mang)) cua truong cong tap doan ca~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) OR (doi chieu)) xanh - ((hanh tang) or (hanh mang)) cua truong cong tap doan ca~".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) OR (doi chieu)) xanh - ((hanh tang) or (hanh mang)) cua truong cong tap doan ca*.
