I have a concern/request.

One of our publishers will potentially be concerned with security issues
of MG indexing. Specifically, we want to reassure them of the difficulty
a hacker would have recreating the source docs from the inverted index
db file. Do you know if a paper exists on this topic. If so, could you
point me to it?

Thankyou,
