A simple search API that would allow a Frontend to update results as a user types. This example will search for schools.

First, add a search method to the School model

            
                def self.search(name)
                    where('name LIKE ?', "%#{name}%")
                end
            
        

Next, add a search method to the Schools Controller

            
                # GET /schools/search?name
                def search
                    @schools = School.search(params[:name])
                    render json: @schools, status: :ok
                end
            
        

Last, add the /search to the route

            
                resources :schools do
                    collection do
                      get 'search'
                    end
                end
            
        

Now search using a full name of a school: /schools/search?name=Test University
