Understanding Search Engine Technology – How Search Engines Work

Search engines are far more complex than they seem. It’s easy to assume Google is a rather simple website judging by its design characteristics. The website features a logo, a search box and a button to submit your search. There are very few websites on the Internet that initially seem as basic as this. However what’s behind the scenes, the true technology behind a search engine, is a rather advanced algorithm and data mining system that takes millions of dollars to operate.

Search engines use data mining to display their results

Every website on the Internet that is to be searchable must first be explored by search engines. This is called data mining. It’s the process of using computer “spiders” or bots to browse websites on the Internet and gather critical information. Information such as that website’s title, description, page content, and its most used keywords. By mining all of this information, Google and other search engines can then use it to display website results to their users.

When you search for a particular phrase on Google, their database with all of the mined information from every website is then accessed and the most relevant websites will be displayed. The algorithm behind which websites are displayed is even more complicated than the data mining process.

Search engine algorithms determine the order of the results

After searching for something on Google you will find many pages of results with about ten results on each page. These are the websites that Google has determined are most relevant to the phrase that you entered. As you may already know, sometimes these results are highly relevant and sometimes Google doesn’t quite get it right. Google has been refining their algorithm that determines the order of these results for years. In fact, they release several algorithm updates every single year and these updates drastically affect which websites get the privilege of ranking at the top.

Search engine algorithm take many factors into consideration and some of these factors include the title of the website, the description, the keywords found within the website’s content, whether images or videos exist on the page, how much content is on the website, the internal linking of the website and whether or not pages are linked to each other in an organized fashion, how old the website is, how fast the website loads, and how many other websites link to it. If big brands and authority websites all provided links to another website, then its rankings would increase because of these links. Links serve as popularity indicators and the more high quality links a website has the better its rankings will be.

Search engines have an “index”

When search engines use data mining to read a website and store its title, description and other relevant information, this website is then indexed in the search engine. This data can be stored in one single place or in a collective database. It means that the website has been crawled by search engine “spiders” or bots and has been added to the “index” of the search engine. Websites can also be un-indexed if they were to go off-line or if the content on the page was removed. This would happen when the bot goes to the website for a second time and recognizes that there has been a change. Websites that are extremely active and get updated with content regularly will be indexed faster by search engines. Search engine bots take priority over these types of sites and they will crawl them first.

This isn’t the only way an index can be stored.

When you use search engines you are searching the index

When you search a keyword or a combination of keywords into a search engine, you are essentially accessing the search engines index database. Every website that has been indexed by that search engine will be accessible by your search. It’s a very powerful feature to have available and that’s why Google and other search engines developed boolean operators to make that even more powerful. You can use strings such as “AND,” “OR,” “NOT,” “FOLLOWED BY,” and “NEAR” to customize your search. You can also search things within quotation marks and Google will ensure that the keywords are searched as a phrase and that phrase must be found within the document or file.

Users of search engines undoubtedly take the technology for granted and it’s important to understand just how complex a search engine truly is. Search engines make it possible for anyone to browse the internet and find almost every piece of information that has been published online.

Behind The Scenes Of Peer-To-Peer Search Engine Technology

We can start counting on our fingers and toes now, to account for the complexity in which P2P networks have been steadily growing. Since networks now have several hundred computers and an equal amount of software systems which are built by components, and distributed to several computers.

The thing is, no one ever stops to think about the complexity of these systems, no matter if they are controlled by one or even multiple administrators. This is a very challenging task. It becomes even more of a task if the system has dynamic properties.

What does this mean? Mobile companies, for example, are forced to cope with extremely rapid changes (as in their structures), as well as in their number of nodes in networking. It’s near impossible for a human to react to these high-frequency changes, and maintain them all. Because of this, alternative approaches are constantly being developed.

Search Engines Who Focus on Our Privacy

As you become more familiar with P2P networks, you should start to notice that they can also be accessed by SSL, or https. All this means, is that your searches are being encrypted 100% between you, and the search engine you are using.

If you are one of the paranoid peers who worry about cookie storage or the like, you can use most of these peer-to-peer search engines in a personalized manner, by simply switching your filters around. You have access to change things such as your languages, family-filters, and more. This is done by accessing a search engine though a “special” URL (parameter).

What Peer-to-Peer Search Engines Offer

The concept is actually quite simple when you understand what it is you are dealing with. One way to approach this is by thinking of a P2P network as a standardized browser connecting to a web search. If someone were to search for a small file that not many people may be looking to download, chances are they will be able to complete the file sharing with no issues.

However, if someone were to look up a larger file that was in demand by many peers, each peer would want to download it, many at the same time. This can be time consuming to download, and this is where the issues begin, and P2P has been designed to address problems just like this.

If several clients already have a copy of the file which is in demand, they hope to find multiple copies of the file (from multiple clients). This can eliminate the “bottleneck” effect of server. If a clients file-source is busy, unavailable for whatever reason, or simply offline, another file from a separate source can then be obtained. Thanks to these peer-to-peer networks, we are even able to change the process for downloading these files (in P2P), which can employ just about the same outlook on protocols which are used by client-server-like systems.

File Sharing & Peer-to-Peer Search Engines

Peer-to-Peer file sharing is exciting, it’s new (enough), and it’s all based on our knowledge of technology. With P2P file sharing, nodes are able to deliver large content files to multiple users (peers), which are distributed through a P2P network. A more traditional file server uses a large amounts of bandwidth, which are consumed to send files from one central location. In contrast, a peer-to-peer client is able to obtain files from any client who has copies of the file on hand (think Utorrent, Bittorrent, Limewire, – even FaceBook uses P2P to allow searches throughout its network). You can find a large list of the most popular P2P networks used today here: http://peer-to-peer1.software.informer.com/software/

What Problems Do P2P Networks and File Sharing Face?

One of the major problems we still face with any peer-to-peer network is allowing clients to locate the files they need to download the content they want. Because we are able to locate files from other members (clients) within the network, we must come up with an efficient way to find them, which is the base of a good P2P system – it’s ability to perform [well].

Sean Parker and his colleagues were among the first of those who created ‘first-generation’ P2P networks like Napster. These types of networks were established to use a centralized-file-registry. This registry contained a number of servers which carried information about locations of files (of active online clients). When someone located a file they wanted to download, the central server had to be contacted, which then brought up a list of files the client had available to share. Since the first batch of problems creases have been ironed down to a minimum, we still face new arising challenges as technology grows and changes.

Overall, we can see why these peer-to-peer networks are so popular and continue to rise: lower bandwidth charges for each content providers’ server(s), as well as faster download times. We clearly have a few bugs to work out still, what with the headache ISP’s face: heavier loads on much lower bandwidth. Engineering networks which can serve standard client-server nodes as well as P2P nodes are substantial challenges, indeed, but with the growing need to share and download files, we are well on our way to perfection.
