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