Steps to reproduce:
Default search Limit for search and filter results: 1000
If we have more maintenances then configured limit.
Clicking on Order by Active since

Result:
That does not guarantee to see a proper result based on (ASC/DESC),
Because query is formed like

ORDER BY m.active_since LIMIT 1001 OFFSET 0

So the output is always ASC and cropped if exceeds filter limit.

Expected
Order by should change to ASC or DESC based on frontend setting.
