Avamar Reporting

we have a PowerShell script that allows us to search the Avamar backup for certain keywords, and then exports a DI showing the files that the keywords hit on in the filename, as well as an export of the folders and files which contained the search terms in the file/folder name.  Are there any scripts (via PowerShell or other) which will show the date the search was conducted, the search terms that were applied, the field-server and time-stamp of the backup that was searched ?  Further, would it be possible for a PowerShell script (or something that queries the SQL backend) to allow us to search on a date range (possibly based on a file last modified date of eFiles or some medata property of msg's such as date sent / date received , and show the date last modified, author, etc basic metadata of files that contained a keyword hit, or msg's that contained a keyword hit ?   It is critical to us to show the defensibility of our PowerShell keyword search process through some type of reporting that can be exported (whether in the form of a DI.txt or CSV, etc).  Is this something that a script of some sort could easily query from the SQL backend and export to some sort of formatted result ?   Obviously I'm not as technically proficient as most of the people reading this inquiry, so any critique of my somewhat rudimentary thought process is certainly welcome, and I certainly would not take offense.  Any advice / helpful input would be so greatly appreciated !
