I'm trying to limit the searching distance so that structures can only be found if you're about 64 blocks close to them, so I used the config file.
However, the variables that affect the searching distance don't seem to be working correctly.

At the moment, I have "maxRadius" and "maxSamples" both set to 4 because at 64 radius it definitely didn't work. (honestly I've no idea what those two numbers mean... four what? what are samples??)

With the 4 value on both options...
For the vanilla minecraft structures, it seems to be finding them at about 150 blocks of distance, tested with a desert pyramid.
But for modded structures, it seems to be finding them from much farther away. Cobblemon Megashowdown's mega sites and megaroids were both being located from 400+ blocks away, pretty much always finding one no matter where I went.
