# Triggering this exception is slightly magical. We need to
# - first create a query, and from it a messages iterator
# - then modify the database "enough"; it's not totally clear how much is
# enough, but adding the LKML corpus emails and doing some light tagging
# seems to work
# - finally, iterate through the messages iterator, which should trigger the
# DatabaseModifiedError exception
# add default corpus for the initial query
add_email_corpus
# As per above, copy LKML corpus email files, but do not add them to the DB yet.
