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