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