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