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