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