• The words AND, OR and NOT may confuse the search; try adding quotes: "%((((((22radiation induced) or (((friction injuries) OR (frictions inquiries))))) or (amputation injuries))) or (radiation induced)) %2f therapy%22".
• Adding a wildcard symbol may retrieve word variants: %((((((22radiation induced) or (((friction injuries) OR (frictions inquiries))))) or (amputation injuries))) or (radiation induced)) %2f therapy%22*.
