SearchEverything how?

I have been trying to get some sort of search functionality on my blog. And let me start by saying I’m totally new to this, but I am usually able to search and find solutions to most problems online, but when it comes to the Searcheverything plugin for WordPress I haven’t been able to find anywhere how to get the thing on to my sidebar. I am able to install the plugin and get it to work the way I want, but how the hell do I get it to actually show on my blog and now just in Site admin?

I assume this is a total newbie question since I am unable to find any instructions on how to do this. This must mean that everyone else knows how to do it without having to ask.

Any help would be appreciated. Thanks
