Searching Site Content Using REGEX Patterns

Question

Intent: Detect content in SharePoint 2013 lists and libraries that matches a REGEX pattern, like social security numbers.
SharePoint 2013 only exposes KQL and FQL languages. 
http://msdn.microsoft.com/en-us/library/office/jj163973.aspx
I am comfortable writing this as an App.  I do not know how to pass the search index through a REGEX match.  Perhaps there is a way to access the data on more of a server model instead of through the client APIs?

Hi  Eric,
For achieving your demand, you can write a Content Enrichment Web Service to extract regex patterns from a managed property.
Here is a blog you can refer to:
