It seems likely that those who are in control of the data sources would
be maintaining some kind of delete log, and that they should be able to
make those logs available to you.
For my index, the data comes from a MySQL database. When a delete is
done at the database level, a database trigger records the old
information to a main delete log table, as well as a separate table for
the search system. The build system uses that separate table to run
deletes every ten minutes and keeps it trimmed to 48 hours of delete
history.
