How to turn off search indexer?

Hello,

This file

C:\ProgramData\Microsoft\Search\Data\Applications\Windows\Windows.edb

is constantly growing up. I assume it contains updated search index of all files.
I'd like to turn it's updating completely off to spare some resources.
I can locate a Windows Search service which is set autostart but I think disabling this service will result in disabling searching within start menu and control panels (which I don't intent).
Is there a way to disable permanent indexing of my hard drive while keeping the start menu search available? Thanks in advance

Thanks
One more question, will this disable also search through start menu and control panel?

nope it will still work, but a little bit slower (obviously because it doesn't have a index), i have mine turned off to maintain my hard disk, start bar search/control panel search will still work don't worry about that :)
