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