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