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