• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((chieu xanh) OR (chieu sang)) - hanh trang lam nhung song van ((tan tap) OR (han tap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((chieu xanh) or (chieu sang)) - hanh trang lam nhung song van ((tan tap) OR (han tap))~".
• Adding a wildcard symbol may retrieve word variants: hoc ((chieu xanh) or (chieu sang)) - hanh trang lam nhung song van ((tan tap) OR (han tap))*.
