• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu sang - thanh ((thanh cua) OR (hanh cua)) nhung tong tap ((toan tap) OR (doanh tai))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sang - thanh ((thanh cua) OR (hanh cua)) nhung tong tap ((toan tap) or (doanh tai))~".
• Adding a wildcard symbol may retrieve word variants: ho chieu sang - thanh ((thanh cua) OR (hanh cua)) nhung tong tap ((toan tap) or (doanh tai))*.
