Steps to reproduce:

1. Create 50+ web content articles that all share a similar term
2. Create a result ranking using that similar term as a search query
3. Look for a 'Load more results' button
   Expected result: 'Load more button' should be available on result rankings page and clicking it should load more results.
   Actual result: 'Load more button' is not present and the page shows a maximum of 50 results
4. Look up the same search term within 'Add Result' modal (or just search for "*")
   Expected result: Pagination past the first page within the 'Add Results' modal should be available.
   Actual result: Cannot paginate past the first 50 results or whatever variable number of results is set to show up per page (5, 10, 20, etc)
