Thanks for the idea. I ran into trouble with a wall texture that was too low-res for closeups, and now I have an idea how to tile a bump map using the function editor. I just tested the idea, and it works. Actually, it's quite simple. Just enter the function editor, and select the UV coordinate node that's connected to the bump map. Change xScale and yScale to lower values than 1 (I used 0.5) to tile the bump map. Do the same for the UV coordinate node connected to the texture map, and you'll have a tiled texture/bump map. I've kept the mapping mode for both bump map and texture map at Automatic.

The pen is mightier than the sword. But if you literally want to have some impact, use a typewriter
