• Performing a fuzzy search may retrieve terms with similar spellings: (("advanced computation using diffusion problem") OR ("using modis python python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"advanced computation using diffusion problem\") OR (\"using modis python python programming\"))*".
• Removing quotes may allow a broader search: (( advanced computation using diffusion problem ) OR ( using modis python python programming ))*.
