When you delete a search project, you can either delete the environments and customization data associated with that project, or detach them from the search project.
Note that you cannot delete a Production project if it has linked projects. You must first delete the linked projects, then the Production project.
On the Projects tab, click Projects.
Click the project’s delete icon ().
In the dialog box, select items you want to delete along with the project.
Note: Any items that you do not delete can be reused by other search projects.
Click OK.
