• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu xanh - ((hanh mang) OR (nhanh mang)) va nhung xuong dan ((thanh lap) OR (thanh san))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - ((hanh mang) OR (nhanh mang)) va nhung xuong dan ((thanh lap) or (thanh san))*".
