• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"coder vector coding data parallelism\") OR (\"on python python python programming\"))~".
• Removing quotes may allow a broader search: (( coder vector coding data parallelism ) OR ( on python python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("coder vector coding data parallelism") OR ("on python python python programming"))*.
