• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"advanced oxidation _ computing program\") OR (\"based computational in computer program\"))".
• Removing quotes may allow a broader search: (( advanced oxidation _ computing program ) OR ( based computational in computer program )).
• Adding a wildcard symbol may retrieve word variants: (("advanced oxidation _ computing program") OR ("based computational in computer program"))*.
