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