How to view the original file names for .mht files archived with File System Archiving (FSA)

Description

When .mht files are archived with Enterprise Vault (EV) FSA they may not be searchable by Name/Subject if that name was modified from the original page name.  

For Example:  A file named {9e0ac6ab-4620-49a4-b0af-043f4bf02b3b}.mht is archived and then displays the Name of Unable to add an Enterprise Vault... when viewing in Enterprise Vault Search (EVS).  To view the original name, the EVFSA.OriginalFileName index property can be added to the view and searched in EVS.  

To add the column and search, do the following: 

1. Open the EVS page in a web browser. Example: https://ev1.ev.local/EnterpriseVault/Search/Shell.aspx
2. Right-click on the column header and select Columns > Customize Columns. 
3. Check one of the unused Property Name values and choose Other from the drop-down menu.  
4. In the Property Name field, enter EVFSA.OriginalFileName.
5. In the Column Header field enter a name such as Orig_name and click Done. The field is now displayed in the EVS results. 
6. To search for the item, use the format EVFSA.OriginalFileName:FILENAME. An example is shown in the above image: EVFSA.OriginalFileName:{9e0ac6ab-4620-49a4-b0af-043f4bf02b3b}

Note that the search criteria will be highlighted if found.
