Thank you for your question on WordPress search widgets. The title of your question sounds as if you want a widget to search only on the active page. I am not aware of a widget that does that, but pressing ctrl and F at the same time will enable that feature on a Windows machine.
As for a search function for your blog where a visitor can enter a word and find a blog article on your site. The default WordPress search widget will do that.
