A bit late but hopefully useful.
Why not try some of the third party tools that can be integrated into SSMS.
I’ve worked with ApexSQL Search (100% free) with good success for both schema and data search and there is also SSMS tools pack that has this feature (not free for SQL 2012 but quite affordable).
Stored procedure above is really great; it’s just that this is way more convenient in my opinion. Also, it would require some slight modifications if you want to search for datetime columns or GUID columns and such…
