i dunno about howto make them but i know for getting new site information you need a crawl bot or somethin like a spider. If you get logs of who has been on your website you'll notice somethin like

crawl-##-##-##-##.googlebot.com

b3091325.crawl.yahoo.net

 

This is that website getting your information.

A lot of Google's web crawler is written in Python I think. Making a search engine CAN be made in just php/mysql (I think) You will need to create a web crawler, and have it crawl websites. You then need to store the information on your server, and create a good searching algorithm to return results. Just knowing PHP/MySQL may not be sufficient though

 

I suggest you check out this tutorial and try to implement a search feature into your own website before trying to make a search engine. its not easy
