This list is called a search engine results page (SERP).Search engines are able to return results quickly.It enables users to locate information on the World Wide Web. Popular examples of search engines are Google, Yahoo!, and MSN Search.
What is Index An index is another name for the database used by a search engine.It contain the information on all the websites that Google (or any other search engine) was able to find. If a website is not in a search engine's index, users will not be able to find it.

Indexing: Store and organize the content found during the crawling process. Once a page is in the index, it’s in the running to be displayed as a result to relevant queries. Ranking: Provide the pieces of content that will best answer a searcher's query, which means that results are ordered by most relevant to least relevant.
