• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu xanh - hanh trinh cua ((nhung cong) OR (((hang cong) OR (bang cong)))) van thanh cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - hanh trinh cua ((nhung cong) or (((hang cong) OR (bang cong)))) van thanh cao~".
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - hanh trinh cua ((nhung cong) or (((hang cong) OR (bang cong)))) van thanh cao*.
