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