•Spider
•Crawler
•Indexer
•Database

Thats the most simplest form of description for how search engine works....
Very simple, just 5 of them.

Honestly, so simple to understand and teach someone.... but I thought spider and crawler were same....!!?

It will be very nice if you can write down in detail about each of these components

You have mentioned the names, but to understand what each of these components are, we need to know about them in detail.

I can't see the difference between spiders and crawlers. Can you expand a bit?

Web search engine - Wikipedia, the free encyclopedia

Hope that tells everything about search engine.

Each search engine has its own algorithm, but all search engines take into account keyword density and back links of a website.
