Over 350GB of files in all formats. Searching with ElasticSearch works well, but when more than 10 results are found and displayed on several pages, it's often not possible to click on the "Next Page" button until the last few pages. It usually blocks around page 5, but can sometimes be higher or lower, or even not block at all.
