If you of the "Searches" side tab and then try to enter a new search for a rating you can choose id you want to find a photo which has exactly a specific rating or a lower or a higher rating than the one given in the dialog.

The english terms in "Search rules" for this are:
At least
At most
Equals

The german translation (fisrt 2 entries) mean something very different and is hardly understandable:

Zuletzt       (=> last )
Am häufigsten (=> most frequently )
gleich

I tried to translate these wrong items back into english, thats what I wrote in bracket. The translation should be:

Mindestens
Höchstens
Gleich

Thanks
