Indexing is the process of making records of all fetched webpages and save into big database from where it can be later be recovered. To index your website

You have to create an XML sitemap for your website and submit to google webmaster tool.

Retrieval

In this step, results are to be served to us but it is not so simple process. There are millions of web pages of single search keyword and which webpage should be displayed on the search engine is a big task.

 Some algorithm is there in which the ranking of the pages has to be decided means which page should be displayed in the first rank, second rank, and soon. It requires a fraction of seconds to display the most relevant pages.
