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