Searching Wygwam content returns no results

I've a channel which includes a WYGWAM field, the field is set to searchable and has been set in the collection to be searched and I've regenerated the search index of the collection. Searching for the title of the entry returns a result, however, if I search for any content within the mentioned WYGWAM field I'm getting no results.
