Hi there, i have a lot of question to ask.

first, i'm really noob about SEO and the optimiation word, what does it mean?
2nd, what programming language did google use to create such a great search engine
3rd, is there any one know how to code search engine, ( i think googlue is creating SE doesn't he?)

i really want to have my own search engine, i hve look many of e-book, but non of them satisfied me. Do anyone have links to good and free "how to build search engine" book?

I can't help with the Google question and how to build your own, but the above link takes you to a site that should answer all your questions about SEO (Search Engine Optimization).

You can go to http://www.google.com/searchcode.html for code to put a Google search bar on your site if you want it now or you find out that coding your own would be too hard. But on http://www.google.com/services/websearch.html, they say "(Google reserves the right to sell ads on all Google Free search results pages.)"
