i tried the linke posted by jlhaslip
it is not free

if you see carefully, you will see these steps:

1. Set up your search engine
2. Try it out
3. Provide contact information
4. Purchase your search engine

if you are talking about another link, post it here, i will chek that also.

Ah, sorry, didn't look at the link long enough. Here is the link I thought it was: http://www.google.com/cse/

As Virtual said, just do a search for "free site search" -- you should have a lot of options to work with.

All the data in my website is updated, I have deleted the old data and uploaded the new one
But in my custom search I still get results from the old contents
If I click on that, I get “HTTP 404 Page Not Found”
Search does not link my new contents in site.

how much time will it take, Hours or days?
