how google works

how google works? How do search engines like Google bring the information we are looking for in less than a second? Have you ever wondered how it works?


The search engines have three actions to deliver fast and accurate search results. By scanning the Internet continuously, you can find pages, read and index the search and bring the appropriate results to the user. More than three? No, there's basically a trio of search, benchmarking and ranking, others intermediate operations.

The phrase, called "spidering", means that the network and spider relationship, like the search engine's nest, is wandering around and knowing what's happening. Basically, we can call the Internet. The algorithms that do this work, analyze the source code by reading the Web sites, and follow the links are very specific. They save these pages and then analyze them in a detailed way. There is also a way to write programs that are called "web crawler", "Web Robot" or "bot" on the internet, but the intricacies of the work are the secrets of successful versions of search engines.

Fast opening, fast indexing...

Data obtained from the bots are analyzed and listed

As a bot follows the links on the Internet, let's say it's a picture. There are different size options to see on the official site. This increases the number of addresses the bot needs to visit. When you say multiple image sequences, thumbnail sizes, file format options, their variations grow exponentially as numbers. Considering that the internet is a giant, constantly growing place, it is understandable how difficult it is for programs to constantly roam and learn about the content. Google is constantly expanding its capacity to scan the Internet by investing in hardware and software without years.


Google has surpassed its competitors in both this area and delivers fast and accurate results through fast indexing. It's already gaining simplicity in Google design. A page that opens very quickly. The ranking algorithm works very well because the results are as consistent as fast. It's different from your competitors than good work, but we'll take this farka later.

Classic Search engines Copy a list of words on the Internet pages they are copying and the number of words used in each word, taking notes on a table of importance. This allows the program to top up the results of the searched words most in search results. Of course, it seems so easy to say that. But the problem is that in every language that is used, the presence of the words is attached and drawn. Adding and punctuation marks the Internet addresses, and the small different spelling of words causes them to be perceived as separate words. To fix this, the rule is written on the rule and more sensible results are emerging.


The main problem of this method is that sites that are aware of the method are filling the sites with very sought-after words by cheating to attract more visitors to them. But that doesn't disassemble Google.



Google and increasingly simplified listings


Numbers are stacked against the listed words. These numbers in the index are the document number. The word key is that there are documents across the street with that key. From the list of words in each document, we have come to this state of usage weights. Now the list is reversed and the weight of the words is reflected in the ranking.

Now there's a huge list of words, looking at the searched words from here, and getting the corresponding document numbers from the other table with the numbers assigned to them by the document names and addresses, as a result of the search by the user Fetching addresses. This main index can be compressed because the data that corresponds to the words is a direct document number.


The compression method is also preparing a giant Bitmap instead of storing the numbers. Instead of typing numbers, the row and column number are filled in or blank to indicate the word and the number that is equivalent. That makes it a huge amount of space. Because most of the words in the painting don't have too many documents. For example, in a search engine that indexes trillions of pages, such a picture is 130 GB. When pressed, it holds less and is very convenient to compress because the majority of them are empty as we just said.



Great amenities provided by the Bitmap

Moreover, this compression method makes it easier for multiple words to be searched. In rows and columns on the BITMAP, these two or more words and documents that are searched can be easily found and imported. Occurs when a new Bitmap that contains only the results that are searched appears.

In a giant search engine like Google, bitmaps can span multiple servers. There are many more copies of these. Nevertheless, this method is incredibly shortening the search time. When this "inverted file" indexing method is used for PDF, Office, and e-mail files at a user's house, the call times are still shorter. Google Desktop is already doing this for the desktop.


An important point about searches on the internet is that users often only look at the results on the first page. According to the first search results, if the user does not see a close result of the call immediately, it is called again by changing the words they are looking for. Patient users even examine the most first few pages of search results.



And the main difference is hidden in this word: PageRank


The scheme of PageRank theory

On Google's notice, Sergey Brin and Larry Page publish an academic article at Stanford University. In Turkish, the name is "Anatomy of a large-scale hypertext network search engine". They've drawn the prototype of the new search engines here.

The search engine's name is Google. This is Googol's misreading. Googol means the hundredth force of 10. That's how we illuminate the mystery of the name. Brin and Page decide to use an algorithm called PageRank to make the search results better. Itbears the name of Larry Page.


It was very surprising that sites that wanted to top up the PageRank pages were filled with keywords. Thanks to this algorithm, Google was bringing the results of the works to the users with great consistency. Actually, he's still bringing it. So what's the secret to PageRank?


PageRank is a system that is indexed in order of importance by examining the links of sites. A site showing a lot of links, as a source, is high in PageRank. That site is being moved to the top queues as a resource. Important sites also make them more important when they link to other sites. As a result, the most exploited sites are the top of the content. Users can also find what they are looking for from the original source. It's not always the perfect work, but it's the most effective method ever developed.



Google 10, Wikipedia 9

The PageRank assigned to a page is actually not just the order of importance, if you have to tell me a bit more. A user who is browsing certain pages is also involved in the possibility of visiting that page in the next step. These relevance links reveal realistic results.

A formula that is Google's trade secret is that the PageRank is set between 0 and 10. The PageRank of the 0 is new sites that have not yet been shown much resources. For the time being 10, there's only Google. Wikipedia, Twitter and Yahoo! have a PageRank 9. Facebook is staying at 8. Ultimately, thanks to the importance and quality order, users can easily reach their needs. The chip Online you are currently reading is among the major, top-level sites on the Internet that have PageRank 7.


Instead of quantifiers, PageRank is a system that attaches importance to the importance of pages and works by measuring the weight of prevalence. That's how Google succeeds, today thanks to this invention, Microsoft is competing. The search engine holds a 65 per cent slice of Google, of course, not only does it work with this algorithm. Google's server farms, the money and time that it devotes to this work are also incredibly. Thus, unless a much better algorithm is developed, it is very difficult to rival Google unless there is a capital and power like Microsoft behind a new search engine. The magic formula is working very well for now and now you know how it works.
