• If you are trying to use Boolean operators, they must be ALL CAPS: %((((22radiation induced) OR (computation injuries))) OR (radiation induced)) %2f therapy%22.
• Adding a wildcard symbol may retrieve word variants: %((((22radiation induced) or (computation injuries))) or (radiation induced)) %2f therapy%22*.
