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