How Do Search Engines Function?

Search Engines Function are computer programs that help us find the information we need as quickly as possible without getting lost in the vastness of the internet.

A search engine must first “see” the data on the internet in order to respond to queries sent to it.

In other words, a search engine can only show you pages that it has previously “seen” and “remembered.”

He cannot present pages that he has never seen before or that he cannot recall seeing even if he has.

However, how does a computer perceive and remember pages? You’ve entered through our front door.

Pages on the Internet are linked to one another via links.

How Do Search Engines Function

It is possible to navigate from one page to another in this manner.

Furthermore, pages typically link to pages that are related to them.

For example, it is highly unlikely that you will find a link to a French page about cat food on a Turkish page about heart surgery, as well as on the site.

Search engines take advantage of this feature and begin surfing the internet from a site.

When they see a page, they examine it and attempt to comprehend its contents, just as a user would with a browser like Web Explorer or Firefox.

Then they save the content somewhere in their memory (hard disk) and follow the links on the page to other pages, where they repeat the process.

As a result, while browsing the internet, they visit the site as many times as they can in order to remember it.

The words on the page are the primary means of remembering the pages.

They keep the words we leave behind on the page in lists called “Index,” such as the contents at the beginning of a book or the index at the end.

As a result, they try to remember which word is on which page.

More advanced search engines consider the frequency (number) of words we leave on the page, their position on the page, their relative position to each other, the words used for external contacts within the page, the page title, the titles on the page, the words written in upper and lower case letters, the color size of the texts, and the site-wide predominance. Many features, such as the issue, the content of other pages that link to the page, and the content of the page’s linked external links, are handled by them and stored in indexes.

The goal of indexing the page in order to preserve it is to provide easy access to the data on the page when needed.

Even though we have the entire book in our hands, we still need the table of contents to construct an analogy.

When looking for a subject in a book, we first look at the chapter titles, page titles, and so on.

Or, if another book is referred to in a book that is important to us, we consider it relevant and try to review it if that book is available.

In this case, search engines apply a similar concept to web pages and sites.

When a user enters a query, search engines immediately look through their indexes to find pages that contain the words we left out of the query.

Then they sort the pages based on various criteria and display the results to the user.

To summarize, search engines are made up of three parts.

The first component is the crawler (crawler) or spider (spider) in English, which navigates the pages and collects their content.

The second module searches the content of pages collected from the internet and hides it in the indexes.

The query module finds the user’s queries in the indexes created in the second section, sorts them, and displays them to the user.
