Permissions to add managed or crawled properties

Question

What are the permissions required to modify/add a managed or crawled property in Sharepoint 2010?

EDIT:
programmatically

Answer 1

You can use SPSecurity.RunWithElevatedPrivileges. this is a delegate method that is to run with elevated rights. This method runs under the Application Pool identity, which has site collection administrator privileges on all site collections hosted by that application pool.

For example:

 SPSecurity.RunWithElevatedPrivileges(delegate()
      {
            // Elevated Permission Code Goes Here
      });  

This way you do not need to grant special permissions, just wrap your code with the method above.
