As I was looking into the implementation details of the `/t/:tag_name`
relevancy feed I noticed an instance variable that we do not need.
Below are the results of looking for the instance_variable
`@article_index` or a potential `article_index` local variable or method name.
```shell
❯ rg "@?article_index"
app/controllers/stories_controller.rb
28: @article_index = true
131: @article_index = true
162: @organization_article_index = true
app/controllers/stories/tagged_articles_controller.rb
18: @article_index = true
app/controllers/stories/articles_search_controller.rb
7: @article_index = true
app/views/articles/_single_story.html.erb
26: <% if story.cached_organization && !@organization_article_index %>
32: <a href="/<%= story.cached_user.username %>" class="crayons-avatar <% if story.cached_organization && !@organization_article_index %> crayons-avatar--s absolute -right-2 -bottom-2 border-solid border-2 border-base-inverted <% else %> crayons-avatar--l <% end %> ">
79: <% if story.cached_organization && !@organization_article_index %>
