• If you are trying to use Boolean operators, they must be ALL CAPS: doi chieu xanh - ((thanh tung) OR (thanh cong)) ((sau thong) OR (ca trong)) dong doanh phan tu~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chieu xanh - ((thanh tung) OR (thanh cong)) ((sau thong) or (ca trong)) dong doanh phan tu~".
• Adding a wildcard symbol may retrieve word variants: doi chieu xanh - ((thanh tung) OR (thanh cong)) ((sau thong) or (ca trong)) dong doanh phan tu*.
