• Performing a fuzzy search may retrieve terms with similar spellings: (("coder duplication model algorithm array") OR ("via python python python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"coder duplication model algorithm array\") OR (\"via python python python programming\"))".
• Removing quotes may allow a broader search: (( coder duplication model algorithm array ) OR ( via python python python programming )).
• Adding a wildcard symbol may retrieve word variants: (("coder duplication model algorithm array") OR ("via python python python programming"))*.
