• If you are trying to use Boolean operators, they must be ALL CAPS: ((((((((cppakkplan OR cpplean) OR pland) OR cpplan) OR aplan) OR lan) OR can) OR clar) OR lean).~.
• Adding a wildcard symbol may retrieve word variants: ((((((((cppakkplan or cpplean) or pland) or cpplan) or aplan) or lan) or can) or clar) or lean).*.
