At present in Clearwell using the participant picker I can search for emails where:

- sender is Fred Bloggs

- receipient is John Smith

BUT this returns any emails that John Smith was a receipient of (eg he was copied or other people were copied in on the message).

It would be very useful to be able to search for emails specifically between two (or more) individuals but only those, so the results would only be messages that the selected individuals were included. So the search could be:

- sender is Fred Bloggs

- receipient is John Smith

- only specified names

Another way of implementing this could be to specify the number of receipients of the message so

- sender is Fred Bloggs

- receipient is John Smith

- receipient count=1

Quite often in an internal investigation Fred and John might send lots of emails including other members of their team but for the purposes of the investigation we are only interested in what they sent to each other.

Hopefully that makes sense!
