To know all that process, let’s see how search engine work step by step to understand it in a proper and easy way.
What is a search engine?
To understand how search engine work in a better way, first of all, we have to understand what is a search engine. The search engine is basically a web-based mechanism or method of searching information through the World Wide Web. Search engine gathers all the links and websites related to the term you enter in the search bar and presents your result in a list or index. The internal algorithms of the search engine decided which website will rank on the top. The search results do not consist of text only. It contains all related infographics, images, videos, research papers, surveys and articles. Some popular search engines are Google, Yahoo, Bing and DuckDuckGo.
How does a search engine work?
Below we will discuss how search engine work step by step to understand best. For a search engine, URLs are the most important and compulsory thing. The most essential and primary three functions through which search engine works are: crawling, indexing and ranking.
It would be not wrong to say that the search engine is all about URLs. First of all, the search engine compiles all of the known URLs sent to the scheduler. Then they make the decision when to crawl a website which is the first step in the working process of search engine. The scheduling of document identifier is also done by the scheduler.
Step #1 Crawling:
The first step is crawling. If you are doing any project or assignment, what would be your first step? For sure, you will gather all the information and related content first. Same as the first step, the search engine is also like that. In crawling, the crawlers or spiders, which are the team of robots of the search engine, are sent to gather and find all the new content. The new range could be anything a picture, webpage a video, any document, new PDF, survey report, graph, infographics or charts. But the only requirement for that new information content is that it should be discovered or opened with a link. Because the search engine is all about URLs, all the information and content are easily accessible through a link, website or URLs. Then all of these new links are added to the index, which is known as Caffeine so that these links can appear in the search result whenever a searcher for content related to that link or the information in the link matches with the query. This crawling helps the search engine keep its content and information up to the date because, after every few days, the spiders and crawlers go for the new web pages and links.
Step #2 Indexing:
After the crawling, the next step begins, which is indexing. As we have discussed above, the search engine adds all the new links and web pages into the index. It clearly shows that the index should be a list of all the URLs and links. And all the process in which the task is done is called indexing. But it is not that easy. For instance, all the links are not directly added to the index once the crawlers have searched them. Before this, a complete process of analyzing that connection is made. The search engine learns in detail about every page and its content. The search engine analyzes every picture, video, graph and text of the link to learn about the page. When the search engine understands the data of the page entirely, it added the link into the index. The index is the vast database that has trillions of web pages and links stored in it.
Step #3 Ranking:
The third and final step is ranking. When all the new web pages are searched and are added to the index of the search engine, then the process of ranking these web pages and links started. Whenever you search for anything on a search engine, in the result, you got a long list of different web pages that have relevant information related to your query. In that long chain of results, few pages are on the top, and also there are web pages shown on the bottom or second and thirst page of your search engine. The reason behind this is when a searcher searches anything on the search engine, the search engine goes through all the links and webpages present in the index and then show the best and most relevant result on the top of the list, which has the content for which you are looking for or have the correct answer or solution of your quarries. All the web pages aim to get a higher ranking on the search engine for which they struggle a lot and learn SEO (Search Engine Optimization) techniques that are helpful in the good ranking on search engine.
