How Does a Search Engine Work?

Whether it is the search engine integrated with Facebook, or the more common search engines like Google, Yahoo, Bing and others that you know … they all work on the same principles, more or less. You have searched for information on the Internet before, and depending on how or what you had specified, you got a lot or less search results. Even the Public records search engine, free background check online, and criminal record background check work in the same way; however, the results this time are more narrowed down. This is to get you the information that you need, faster. The reverse phone lookup search works in a similar manner as well.

Imagine if you had to go through strenuous exercises to get information from a site, let alone finding the site. Say for example, you type the keyword “basketball” on your browser, with the intention of getting information about how to play basketball, the number of results you would get might not be that important or relevant in regard to the information that you want. This means that you would have to click on each result trying to find what you want. This is very exhausting to even think about and it is also where search engines come in to play.



A search engine is basically a program which searches the World Wide Web for information that is in line with the keywords that have been specified by the user. It is especially used to find sites and web pages that are optimized with SEO and match the search query. Understanding how search engines work is pretty simple. All you need to know is their functions from which you will understand how they work, as you will see below.

  • Crawling

This is a mechanism made possible by search engine “robots”. The search engine crawls or searches the web for information using links. Such links provide a connection between different documents PDFs or otherwise in the web and make it possible for the engines to identify websites that have the best information as pertaining to the search words used by the person looking for information.

This process happens from time to time as the robot’s crawl, otherwise referred to as spider, the web to look for new pages, more importantly; they identify any additional links to the web pages they had gotten before. The web pages are selected and stored according to their prevalence and popularity.



  • Building an index

This is more or less tied to crawling. This is because once the search engine identifies a preferable web page, and it deciphers this information and stores that which has been selected in the form of an index. The index is a list of sites and web pages that the search engine assumes to be best and relevant. The list is then ranked depending on the site’s popularity, or what the search engine considers as popular.

In the event that you require information, all that you need to do is to type in the keywords of your search in your browser and leave all the work to the search engine. What happens is that the search engine uses a specific algorithm to provide you with a list of the ranked sites from the index. As such, what would have been an excruciating and long exercise of going through every site to get information is made simple for you by the search engine.

Additionally, some search engines are equipped to enhance the personalization of searches by using information it has about the user to provide results. This is to mean that if and when you search for certain information, the search engine can provide a ranked list of pages that are particular to your interests.

There, that is just a brief and simplified explanation of how the public records search engine works. Of course, the process is much more complex, but what is important is for you to know how to get the results that you want, no?
