Mhm, this is surprising (in a negative sense). So is there any way to
know if these deletions have actually affected any documents? How
about indexWorker.hasDeletions()? Contracts of these methods are not
documented well enough and I don't feel too confident to make
independent decisions just by looking at the source code :-(
