I may be wrong, but I think those are per-user indexes, I'm guessing that anything needing search will break for the lucky user you have deleted for, possibly a reindex will recreate them though.

That is correct.

They are the Lucene indexes for user searching. If you do delete them, you can recreate them by executing "zmprov rim <emailaddress>"
