Duplicated Search projects use the same content sets as the original. You may want to duplicate a project if you need to set up another index using similar content and customizations.
To duplicate a Search project:
On the Projects tab, click Projects.
Click the duplicate icon () for the project.
Provide a name for the project.
Click OK.
Customizations associated with your project are not duplicated, but the same customizations are associated with the new project as with the original.
