• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((hieu manh) OR (chieu sang)) - thanh ((tuong cua) OR (thong cua)) thuong phong van thanh cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((hieu manh) or (chieu sang)) - thanh ((tuong cua) OR (thong cua)) thuong phong van thanh cau~".
• Adding a wildcard symbol may retrieve word variants: ho ((hieu manh) or (chieu sang)) - thanh ((tuong cua) OR (thong cua)) thuong phong van thanh cau*.
