AdminCP -> Settings -> Options -> Message Searching Options

and set the first option labelled "Search Engine Enabled" to "No"...this way you can add it back later simply by changing this option back to "Yes" whenever you want, without having to edit or revert any templates. Easy Peasy!

Done, thank you.
I was looking from long time, because this function is not useful.
