Hi @Tara -
Spelling Suggestions are visible only after a query has been submitted and processed. They are a source of suggestions for auto-completion, but you'd mentioned that auto-completion is working as expected.
It's possible that your template doesn't have a placeholder to support spelling suggestions if they are present in the underlying data model.
Examine the response from
//SITESERVER/s/search.json directly - looking for:
The default Freemarker snippet used to render spelling suggestions in the UI looks like:
<@s.CheckSpelling prefix="<h3 id=\"search-spelling\"><span class=\"glyphicon glyphicon-question-sign text-muted\"></span> Did you mean <em>" suffix="</em>?</h3>" />
