• If you are trying to use Boolean operators, they must be ALL CAPS: theo chu tinh - hanh trinh cua ((nhung luong) OR (((nhung tuong) OR (nhung phuong)))) tai toan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chu tinh - hanh trinh cua ((nhung luong) or (((nhung tuong) OR (nhung phuong)))) tai toan ban~".
• Adding a wildcard symbol may retrieve word variants: theo chu tinh - hanh trinh cua ((nhung luong) or (((nhung tuong) OR (nhung phuong)))) tai toan ban*.
