• If you are trying to use Boolean operators, they must be ALL CAPS: doi chieu sang - hanh ((trang cua) OR (tranh cua)) nhung ((thong minh) OR (long tinh)) toan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chieu sang - hanh ((trang cua) OR (tranh cua)) nhung ((thong minh) or (long tinh)) toan ban~".
• Adding a wildcard symbol may retrieve word variants: doi chieu sang - hanh ((trang cua) OR (tranh cua)) nhung ((thong minh) or (long tinh)) toan ban*.
