Simple Search Block adds a block to your application that's only purpose is to render a form with a text field and submit button which will submit to a route (generally a view), passing the text field input to a filter on that route.
This is useful for having a search bar in your site header that you do not necessarily want to make an exposed filter, since that comes with some overhead you may not want to deal with (e.g. sorts or other exposed filters).
