• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"developing computation using cad program\") OR (\"using python python python programming\"))~".
• Removing quotes may allow a broader search: (( developing computation using cad program ) OR ( using python python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("developing computation using cad program") OR ("using python python python programming"))*.
