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