• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"using computation using complex program\") OR (\"using modis from python programming\"))*".
• Removing quotes may allow a broader search: (( using computation using complex program ) OR ( using modis from python programming ))*.
