• If you are trying to use Boolean operators, they must be ALL CAPS: ((toc thien) OR (ton thien)) anh - hanh hang ca ((thong cong) OR (trong cong)) dan toan cao.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((toc thien) OR (ton thien)) anh - hanh hang ca ((thong cong) or (trong cong)) dan toan cao".
• Adding a wildcard symbol may retrieve word variants: ((toc thien) OR (ton thien)) anh - hanh hang ca ((thong cong) or (trong cong)) dan toan cao*.
