The diagnostic tool balooctl monitor relies on signals emitted during file indexing via DBus.
Current monitor only uses 2 signals startedIndexingFile and finishedIndexingFile.

Some changes aren't reflected by those. For example renaming a file or tagging a file. Is this because baloo_file does not see those changes or because the signal is just not emitted?

Should there be a further signal(-pair) to indicate the removal of a file from the database e.g. when it is deleted, moved or renamed? see D4911
