• If you are trying to use Boolean operators, they must be ALL CAPS: hoc chieu sang - hanh sinh vai ((nhung cong) OR (thong cong)) dung ((toan ban) OR (toan cao)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc chieu sang - hanh sinh vai ((nhung cong) OR (thong cong)) dung ((toan ban) or (toan cao))".
• Adding a wildcard symbol may retrieve word variants: hoc chieu sang - hanh sinh vai ((nhung cong) OR (thong cong)) dung ((toan ban) or (toan cao))*.
