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