• If you are trying to use Boolean operators, they must be ALL CAPS: toc hieu manh - ((hanh tinh) OR (hanh trinh)) chap thuong con thanh ((toan tap) OR (toan ban))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc hieu manh - ((hanh tinh) OR (hanh trinh)) chap thuong con thanh ((toan tap) or (toan ban))~".
• Adding a wildcard symbol may retrieve word variants: toc hieu manh - ((hanh tinh) OR (hanh trinh)) chap thuong con thanh ((toan tap) or (toan ban))*.
