Index not showing the results of a search

[Edit] Changed some functions to make it more clear. I am trying to make a search function where the user can input a query, and an API(https://github.com/games-directory/api-giantbomb) returns matching items. However nothing is appearing on my Index despite there not being any errors popping up when I search.

I decided to use the Rails LIKE feature to return the query results in my index as seen below.

  def index
  if params[:query].present?
      sql_query = "name LIKE :query"
      @games = Game.where(sql_query, query: "%#{params[:query]}%")
    else
     flash[:notice] = "No Games Found"
    end
  end

It redirects to the Index, but shows no games nor the flash message. Here is the index: My index.html.erb that is supposed to return a list of games that match the query:

<h1>Test</h1>
<ul>
  <% @games.each do |game| %>
    <li><%= game.name %></li>
  <% end %>
</ul>

I can see the "Test" text, but nothing else after I conduct a search.

For reference, here is the rest of my GamesController.

class GamesController < ApplicationController
//Displays search results
  def index
  if params[:query].present?
      sql_query = "name LIKE :query"
      @games = Game.where(sql_query, query: "%#{params[:query]}%")
    else
     flash[:notice] = "No Games Found"
    end
  end

//Searches through API data
  def search
    @games = GiantBomb::Search.new().query(params[:query]).resources('game').limit(5).fetch
    render 'index'
  end


private

  def game_params
    params.require(:game).permit(:name, :search, :query)
  end
end

My routes just in case that is having any effect.:

Rails.application.routes.draw do
  devise_for :users
  resources :games
  root to: 'pages#home'
  get '/search', to: 'games#search', as: :search
  get '/games', to: 'games#index', as: :index
end

My search bar on my home page:

    <div class="search-font"><h1>Build your Collection</h1></div>
    <div class="container">
      <div class="row">
        <div class="col-md-12 row">
          <%= form_tag index_path, method: :get do %>
          <div class="col-12 col-sm pr-sm-0">
            <%= text_field_tag :query,
              params[:query],
              class: "form-control input-lg",
              id: "typed-text" %>
          </div>
          <div class="input-group-btn ml-3">
            <%= submit_tag "Search", class: "btn btn-primary" %>
          </div>
          <% end %>
        </div>
      </div>
    </div>

What's the issue here? Do I need to revise my index method or is there another problem?
