• If you are trying to use Boolean operators, they must be ALL CAPS: theo chieu xanh - hanh ((tang cua) OR (hang cua)) nhung ((cong van) OR (cong vang)) doan cap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chieu xanh - hanh ((tang cua) or (hang cua)) nhung ((cong van) OR (cong vang)) doan cap~".
• Adding a wildcard symbol may retrieve word variants: theo chieu xanh - hanh ((tang cua) or (hang cua)) nhung ((cong van) OR (cong vang)) doan cap*.
