Search - How to implement the Google website search like the one used here

Question

Hello all,

I would like to implement a search function for my website as the functions listed here

http://stackoverflow.com/search

What should I do in order to do this?

Based on my understanding, two methods can be used to provide search function for my website.

1> MySQL full text search 2> Use search lucene package.

My guess is that the search function here http://stackoverflow.com/search is neither of them. So what is the method that has been used to provide such a search on the website?

Thank you

Just look at the url:

http://www.google.com/search?sitesearch=stackoverflow.com%2Fquestions&q=texthere

It would seem that a MySQL approach would work if your site is entirely database-driven. Otherwise, you need something that spiders, such as Zoom by WrenSoft. http://www.wrensoft.com/
