• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc thieu) or (toc thieu)) tinh - van doanh cua dang cong ngang ((hanh ma) OR (hanh may))~".
• Adding a wildcard symbol may retrieve word variants: ((hoc thieu) or (toc thieu)) tinh - van doanh cua dang cong ngang ((hanh ma) OR (hanh may))*.
