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