To reproduce, open ke_search searchbox, e.g. https://www.hochschule-bochum.de/suche/ and start a search with logical operators, such as
+hochschule +fachbereich
On the results page, notice the total number of results.
Now use the pagebrowser (e.g. click on "Next" or "2"). On the second results page, logical operators (+) has been stripped from the search phrase and the total number of results changes accordingly. This effectively breaks the logical operator functionality.
