sometimes when i'm searching for a particular procedure....i use the following:

use [your DB here]

GO

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 '%YOUR SEARCH TEXT HERE e.g. TABLENAME%'

ORDER BY SO.Name
