Hiding author in search results based on theme settings?

I am trying to figure out how to hide the author in search results.  This article suggests simply commenting out the author's name in search_results.hbs, which of course I can do. But I want the behavior to be controlled by theme's settings (i.e., settings.show_article_author). But when I wrap the HTML in search_results.hbs with the appropriate conditional:

{{#if settings.show_article_author}}
<span class="meta-data">{{author.name}}</span>
{{/if}}

I get an error message trying to save:

not possible to access `settings` in `settings.show_article_author`

I feel like I'm missing something obvious.
