• If you are trying to use Boolean operators, they must be ALL CAPS: toc thien hach - hanh ((trang cua) OR (tranh cua)) nhung cong dan ((toan cao) OR (toan tap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc thien hach - hanh ((trang cua) OR (tranh cua)) nhung cong dan ((toan cao) or (toan tap))~".
• Adding a wildcard symbol may retrieve word variants: toc thien hach - hanh ((trang cua) OR (tranh cua)) nhung cong dan ((toan cao) or (toan tap))*.
