• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"coder precoder design algorithm combining\") OR (\"api python python python programming\"))".
• Removing quotes may allow a broader search: (( coder precoder design algorithm combining ) OR ( api python python python programming )).
• Adding a wildcard symbol may retrieve word variants: (("coder precoder design algorithm combining") OR ("api python python python programming"))*.
