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.
