In scenario like when an index is not useful on one of the many servers, you could delete the index from that single server.
To copy an Index:
Click the Index Management option from the landing page.
Select the NCP server and type of the Index, then click the
button.
Select the Index from the search list and click on the
icon.
Select the desired NCP server(s) where you want to copy the Index and click the
button.
A confirmation appears indicating the Index has been modified.
