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