After posting my first response, I found the full memo.
The scope of the investigation was very limited -- to only emails to/from Hillary Clinton.
With the help of a computer to select out those emails, and filter them against the ones they had already examined, it's likely there weren't many left.
My comment wasn’t on the veracity of your initial response, but meant to emphasize the likelihood of Comey’s folding as a hack. Which I still 100% believe.
