How do you start and stop the Spotlight server in Yosemite?
I'm on 10.10, and I have this service.

$ ls -l /System/Library/LaunchDaemons/com.apple.metadata*
-rw-r--r--  1 root  wheel   1.6K Jul 30 01:33 com.apple.metadata.mds.index.plist
-rw-r--r--  1 root  wheel   1.6K Jul 30 01:33 com.apple.metadata.mds.plist
-rw-r--r--  1 root  wheel   922B Jul 30 01:33 com.apple.metadata.mds.scan.plist
-rw-r--r--  1 root  wheel   856B Jul 30 01:33 com.apple.metadata.mds.spindump.plist


The you can load/unload with this command:

sudo launchctl unload -w /System/Library/LaunchDaemons/com.apple.metadata.mds.plist
