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