Hi!
The problem here is, that the results shortcode is only to move the live results list on the same page as the search is on. Redirecting the results to a page of your choice is not possible unfortunately. WordPress uses a default search results page, and only the theme is able to affect that. The plugin can redirect to that page, and push it’s own results, but cannot affect it’s layout unfortunately.
The two possible options here is to either redirect the more results to the default results page, or use the live loader feature instead, so that the results will be loaded automatically after the visible ones.
