The big headline from Hillary Clinton's news conference Tuesday was that, although she claims to have turned over all work-related emails, she deleted the rest of her emails and it appears there is no way to read them ever again.

But one important point regarding how her team determined which of Clinton's 62,320 e-mails were work-related and which were "personal and private" may have been glossed over...

"This review did not involve opening and reading each email," Time reported. "Instead, Clinton's lawyers created a list of names and keywords related to her work and searched for those. Slightly more than half the total cache -- 31,830 emails -- did not contain any of the search terms, according to Clinton's staff, so they were deemed to be 'private, personal records.'"

...According to that document, here is a summary of how Clinton's attorneys, who were tasked with the job, said they sorted through:

First, a search was done of all emails Clinton received from a .gov or state.gov account during the period she was secretary of state -- from 2009 to 2013.

Then, with the remaining emails, a search was done for names of 100 State Department and other U.S. government officials who Clinton may have had correspondence with during her tenure.

Next, the emails were organized and reviewed by sender and recipient to "account for non-obvious or non-recognizable email addresses or misspellings or other idiosyncrasies."

The results of the searching were that Clinton's attorneys found 30,490 work-related emails and 31,830 emails that were deemed "private and personal."
