• The words AND, OR and NOT may confuse the search; try adding quotes: "recent results in cancer research, fortschritte der krebsforschung ((progres dans) OR (progres de)) les recherches sur male cancer".
• Adding a wildcard symbol may retrieve word variants: recent results in cancer research, fortschritte der krebsforschung ((progres dans) OR (progres de)) les recherches sur male cancer*.
