• If you are trying to use Boolean operators, they must be ALL CAPS: ((doi chiet) OR (doi chi)) tach - hanh trung voi nhung cong dan ((toan cau) OR (toan ban))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((doi chiet) or (doi chi)) tach - hanh trung voi nhung cong dan ((toan cau) OR (toan ban))~".
• Adding a wildcard symbol may retrieve word variants: ((doi chiet) or (doi chi)) tach - hanh trung voi nhung cong dan ((toan cau) OR (toan ban))*.
