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