Bug description

When the total number of search results is a multiple of the page size (5 by default), the search clients can't detect that there are no more results after the current page. Leading the search interface to show a "load more button", which when clicked doesn't load more results. This button does go away once the client receives the empty page.

Steps to reproduce

1. Create 5 files with a name matching a pattern
2. Search for the pattern
3. "Load more results" button is shown

Expected behavior

No "Load more results" button is shown as there are no more results

Start by tracing the search result pagination behavior for a page size of 5 and how the client decides whether to show the "load more results" button. Reproduce the case with exactly five matching files, then verify that the button is absent without requiring an empty follow-up page.
