How to create a search engine like google

I'm new in programming, but I already have 4 months of experience. I'm good in HTML and starting to learn CSS. I want to make search engine like google, that can search in many websites and display the results quick

this is what I already did:

<div id="search_div">
   <input type="text" placeholder="search" name="search">
</div>

how can I do the search? what else I need to know? is there's a ready code for this?

thanks a lot!
