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