Turn off indexing (spotlight)

Just trying to get Mavericks server working, and logged in as an Active Directory user on it. Seems mds_stores is using a large amount of processing. found this post which says to turn it off, in terminal type:

sudo mdutil -a -i off

This is the message in terminal I got when I typed the command in:

/:

Indexing disabled.

/Volumes/Scratch 1:

Indexing disabled.

/Volumes/Scratch 1/Home Folders:

Indexing disabled.

Might be to do with the fact I was trying to get home folders working, something to do with profile manager. Anyway, the command did stop the large processing.
