• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"using combinational code codigo program\") OR (\"using computer code coding program\"))~".
• Removing quotes may allow a broader search: (( using combinational code codigo program ) OR ( using computer code coding program ))~.
• Adding a wildcard symbol may retrieve word variants: (("using combinational code codigo program") OR ("using computer code coding program"))*.
