Sql Server–find some texts in Stored Procedures

I often need to search for some texts in the body of stored procedures. This query can help:

SELECT routine_name, routine_definition
FROM information_schema.routines
WHERE UPPER(routine_definition) LIKE UPPER('%texttobesearched%')
AND routine_type='procedure'

EDIT: just discovered that this method has some problems with long stored procedures; found another one that works better:

declare @searchString varchar(100)

Set @searchString = '%' + 'text to be searched' + '%'

SELECT Distinct SO.Name
FROM sysobjects SO (NOLOCK)
INNER JOIN syscomments SC (NOLOCK) on SO.Id = SC.ID
AND SO.Type = 'P'
AND SC.Text LIKE @searchString
ORDER BY SO.Name
