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