• The words AND, OR and NOT may confuse the search; try adding quotes: "(( solid ((space physical) or (scale physical)) ) or ( ((solid science) OR (said science)) physical ))".
• Adding a wildcard symbol may retrieve word variants: (( solid ((space physical) or (scale physical)) ) or ( ((solid science) OR (said science)) physical ))*.
