Narayana Vyas Kondreddi wrote this proc long ago, but his site is gone. I hope he doesn’t mind if I continue providing his stored procedure here. I recommend you put this in your master database so you can run it from any database.

CREATE PROCEDURE sp_search_code
--drop procedure dbo.sp_search_code

Examples:
To search your database code for the keyword 'unauthorized':
EXEC sp_search_code 'unauthorized'
To search your database code for the keyword 'FlowerOrders' and also find out the number of hits:
DECLARE @Hits int
EXEC sp_search_code 'FlowerOrders', @Hits OUT
SELECT 'Found ' + LTRIM(STR(@Hits)) + ' object(s) containing this keyword' AS Result
2023.3.18 - Added searching of Job Steps
2023.3.18 - Fixed how object schema name obtained to more accurate
