What is "Google"?

Definition: Googol

Pronunciation: 'gü-"gol
Function: noun

Google is a play on the word googol, which was coined by Milton Sirotta, nephew of American mathematician Edward Kasner, and was popularized in the book, "Mathematics and the Imagination" by Kasner and James Newman. It refers to the number represented by the numeral 1 followed by 100 zeros. Google's use of the term reflects the company's mission to organize the immense, seemingly infinite amount of information available on the web.

Originally called "Backrub", the logic behind the Google search engine was develop by graduate students Larry Page and Sergey Brin at Stanford University in 1995. Their first place of business was literally a garage. The garage location was chosen because it had a washer/dryer and a hot tub out back, they were already serving 10,000 searches a day.

So How Does Google Work?
* Crawls and indexes web pages et al.
* Stores copies of web pages and graphics on their caching servers
* Presents users with simple front end to query the database of cached pages
* Returns search results in a ordered fashion based upon relevancy

So What Determines Page Relevance and Rating?
* Exact Phrase: are your keywords found as an exact phrase in any pages?
* Adjacency: how close are your keywords to each other?
* Weighting: how many times do the keywords appear in the page?
* PageRank/Links: How many links point to the page? How many links are actually in the page?

Equation: (Exact Phrase Hit)+(AdjacencyFactor)+(Weight) * (PageRank/Links)

How Do I Get Results?
* Pick your keywords carefully & be specific
* Do NOT exceed 10 keywords
* Use Boolean modifiers
* Use advanced operators
* Google ignores some words:

a, about, an, and, are, as, at, be, by, from, how, i, in, is, it, of,

on, or, that, the, this, to, we, what, when, where, which, with

Google's Boolean Modifiers
* AND is always implied.
* OR: Escobar (Narcotics OR Cocaine)
* "-" = NOT: Escobar -Pablo
* "+" = MUST: Escobar +Roberto
* Use quotes for exact phrase matching: "nobody puts baby in a corner"
