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