Compared to Altavista, Hotbot or MSN, the Google database is almost 2.5 times higher, this is because Google is constantly including content by robots that crawl the Web regularly, renewing and ordering index Google.

Search Features

Google only returns pages that include all search terms. It is not necessary to include "and" between terms. To narrow your search a little more, add more terms.

Google ignores common words and characters known as empty words. Google automatically discarded terms such as "http" and ". Com," as well as certain single digits or letters, because these terms rarely help narrow the search. Neither distinguishes accents, umlauts or the letter ñ. Not case sensitive. All letters, regardless of how they are written, are considered sensitive. For example, searching "google", "GOOGLE" or "Google" will generate the same results.

To provide more accurate results, Google only searches whole words, ie not using the automatic truncation, it just returns the terms that entered into the search box. For example searching for "this" will not return searches containing "statistics" or "stadium". Google searches for words, sentences with the words in the order that we wrote in the search box. The important word order is not symmetrical, it gives the same result searching for "php programming? to "php programming?

Every Google search result contains a fragment of the Web page that shows the context in which the terms appear on this page. Google takes into account the country where you are, even within the same language, is not the same search www.google.es www.google.com.mx that, although always look in Castilian.

No truncated but we can use the asterisk * to replace one, two or more words. Often combined with the operator ("") "* sports store" compare results "sports store").

Autostemming presented in searches. We can also use the operators (+, ', -) as phrase connectors.
