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