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