• The words AND, OR and NOT may confuse the search; try adding quotes: "(( guias 3 hazard transform cities _ ) or ( aguas ((del make) OR (del mazo)) transform pairs 4 ))~".
• Adding a wildcard symbol may retrieve word variants: (( guias 3 hazard transform cities _ ) or ( aguas ((del make) OR (del mazo)) transform pairs 4 ))*.
