Search engines crawl the web and index the documents they come accross, using data mining and information retrieval techniques.
When a user searches for a particular keyword, search engines select all pages which match that keywords and relevance rank them to present relevant results to you

They crawl along web pages and the engine makes an index of them like a book index. It's just metadata for quick searches. You just type a word and it searches the index. Maybe that's not very explanatory and someone else can explain better.

It goes through pages on the internet and pull up each one that has your keyword.
