• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"and computational using sio2 array\") OR (\"using codium python python programming\"))~".
• Removing quotes may allow a broader search: (( and computational using sio2 array ) OR ( using codium python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("and computational using sio2 array") OR ("using codium python python programming"))*.
