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