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