The following excerpt is taken from the FTS team blog which explains new Full Text Search enhancements added to SQL Server 2012 - Denali.
Besides performance and scale improvement, we also added support for property scoped searches over documents with file system properties stored with-in a fulltext enabled table. One can now issue a CONTAINS query looking for all documents containing a particular term and authored by a particular author without having to maintain a separate column for the Author name in the database.
