How to Search the Web
People who are prone to excessive use of beautiful metaphors, like to compare the network with garbage. Like, they all piled in a heap and the devil himself would break a leg. Like, all there is, but that it "all" search, you need to dig the mounds of garbage.Metaphor is beautiful. But wrong. I have on the table prevails, it would seem meaningless pile of useless things. But for me everything on the table subject to the logic of the firm - the most necessary things, like, your favorite cup of tea "bowl" with a displacement of just over half a liter, are at arm's length, the less necessary - further. But to call all this mess or garbage? Discharge!
So the web has its own logic. Knowing and using a few simple rules, you can do so that all information in the web will be at arm's length, and the feeling that the internet - it is trash, will disappear without a trace.
They will discuss search engines and the rules of search on the web.
First - a small lyrical digression, which I will discuss how search engines work. It so happened that the user sees only the interface is a search engine, it may say so, the person inside and - most importantly - remain behind the scenes.
So, the first part of the search engine - a "spider», crawler, search engine robot. It deals with the fact that travel the web, through all the pages visited all the links, not stopping for a moment. Traveling is not just - everything, every page that he looked, "spider" enters into the search engine index as occurring at meaningless words.
The third part, after the index - this is actually a search engine. Is engaged in it that is looking for the right word - or words - in the index. The search engine does not look "all over the internet" - is misleading. Imagine what would happen if it was true: For example, the volume of indexed information on Yandex.ru is 258.67 GB. This means that without the index, after you enter a request for Yandex, he would have to download and view 258 gigabytes of data. This is nonsense. Imagine how many days Yandex would be responsible for your inquiry.
The fact that a search engine does not look "all over the internet", but only in its index, it should be at least two conclusions. First - if the search engine something is found, that does not mean that this is not the web. Second - Search engines differ not only in appearance, but also, for example, the index and the manner of preparation. So if you have not found anything in a search engine, it makes sense to search in the other.
