Content Search filter export/report results
So currently the only option to export results from Content Searches is to either view the very limited preview (which currently doesn't expand the Sender: address to a full email address), and I think might have numerical restrictions, or to export full emails.
We had a business requirement come in that Content Search would've helped us achieve had it had the ability to filter the output emails down to just certain fields.
The requirement was to go back in time searching across all emails in the organisation to get a large list of only the sender domains.
Currently the only way of doing this is to export potentially terrabytes of full emails (in .MSG or .PST format only), download them and run further processing, which is obviously extremely impractical and very time consuming.
If we could instead export or report on just a filtered set of items, eg only Sender Addresses, then we can easily download the resultant file, then we could further process it to extract only the sender domain, and then deduplicate the results.
Obviously to do this properly, you'd would want a comprehensive filter choice on any individual item an email might contain, eg, only want the subject line, only want the attachments, only want the sender addresses (incoming and outgoing) etc etc.
