Implementing proper search is a must for most applications. Fortunately, thanks to Ransack, you can easily add search to your application. In this article, we will show you how to implement search in your Rails application. Note that we are now using Rails 5 for our articles and Ruby 2.3.1. If you are using Rails 4.2, you should be able to follow along pretty easily just by modifying the commands we write. If you have any questions, feel free to leave a comment in the comments section.
