    • 12. HOW SEARCH WORKS HOW SEARCH WORKS Search engines are complex computer programs. Before they even allow you to type a query and search the web, they have to do a lot of preparation work so that when you click “Search”, you are presented with a set of precise and quality results that answer your question or query. What does the ‘preparation work’ includes? Two main stages. The first stage is the process of discovering the information and the second stage is organizing the information so that it can be used later for search purposes.
    • 13. HOW SEARCH WORKS Crawling Search engines have a number of computer programs called web crawlers (thus the word Crawling), that are responsible for finding information that is publicly available on the Internet. To simplify a complicated process, it’s enough for you to know that the job of these software crawlers (also known as search engine spiders), is to scan the Internet and find the servers (also known as web servers) hosting websites. They visit each website and by using different techniques, they try to find out how many pages they have, whether it is text content, images, videos or any other format (CSS, HTML, javascript, etc). When visiting a website, besides taking note of the number of pages they also follow any links (either pointing to pages within the site or to external websites), and thus they discover more and more pages.

    • 14. HOW SEARCH WORKS HOW SEARCH WORKS INDEXING Crawling alone is not enough to build a search engine. Information identified by the crawlers needs to be organized, sorted and stored so that it can be processed by the search engine algorithms before made available to the end user. This process is called Indexing. Search engines don’t store all the information found on a page in their index but they keep things like: when it was created/updated, title and description of the page, type of content, associated keywords, incoming and outgoing links and a lot of other parameters that are needed by their algorithms. Google likes to describe their index like the back of a book (a really big book).
