Enterprise Vault Reports

I've been asked if the following reports could be created for EV - 

1. The amount of emails captured via journaling for a specific journal target mailbox during a specific time-frame. I know there is a canned report that will show emails captured over a specific month but they are looking for something more granular.
2. A report that shows how many times a specific hotword comes up in a scheduled search. 

Any help in pointing me in the right direction would be appreciated.
