When using Arctera eDiscovery's search, the user is not presented the expected number of results as they are filtered. Initially, content is sorted by the From drop down and the program displays 0 results.
If the filter is changed to the To drop down the program returns 20 results. (that are CC'd and BCC'd)
If the filter is then changed to the From / To a user would expect 20 results, but the program returns 0. (Not including CC'd and BCC'd)

The query using the From/To drop down does not include CC or BCC fields.
To generate list of all addresses that include From, To CC and BCC, ensure that both the From and To items are added separately.
