Careful here. There's the Baloo framework which does indeed contain the indexing executables (on Linux) but I'm not aware that those are launched by default. They're not in my "Neon" style KF5 build.
It's my understanding that the Baloo framework provides the basic functionality but that other dependencies (packages) are required to use the search and indexing features.

John: have you tried adding your root directory to the list of locations NOT to search in systemsettings/Search/File Search?

Why would they, none of them is using 32bit fossils anymore ;)

Let me guess, the same dev who would have been dead-set against allowing it outside of Plasma if that were possible? O:-)

Pray tell, which packages and what's the name of the option? I don't see anything relevant in plasma-workspace and plasma-desktop (master branches).

Yes you can: check out the project, do a `git blame` on the file containing the option definition and check the annotation of the corresponding line ;)

Even for the Baloo framework and the indexing executables this will depend how they package the thing.

Last time I checked they don't or include their own fork of an older version that is used only for email indexing. In any case a kdepim dev ensured me that email indexing would work even on platforms where Baloo doesn't (= Mac and MSWin).

Let me guess, you ended up with /usr/usr/usr/usr/usr/usr/.../filenametoolong?
