Please could you put the "Exact Match" feature back, it was very useful.
Consider a stored procedure that has:
Exec Systemx.dbo.QueueEmail @Subject N'Failed to import from source'
Searching "Failed to import from source" with Match whole words only will fail to find the sproc in question, because it considers "N'" to be part of the whole word.
Example: find whole string - ID in (1,4)
