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