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