Larry Page and Sergey Brin looked at Madrid expectantly and in amazement as they told him that he could solve the problems they were currently having in the 'backrub' project. The 'backrub' project is very difficult, and the two of them haven't had a head check for more than 1 year, so they can't wait for this curiosity, and whether the 'backrub' project can be solved perfectly is related to the doctorate degree in computer science of the two.

"According to our research, the 'Backrub' project has many shortcomings, compared to the current mainstream search engines Excite, Ranklink, InfoSeek?...... It's much worse. 'backrub' has two main drawbacks, one is that the core algorithm is not accurate, and the other is that there is no basic search technology. "Madrid's nonsense, what kind of investigation, talking about the high-level, in fact, Larry Page and Sergey Brin and the information about the 'backrub' project were all given to him by Liu Si himself.

Investigation intelligence system Liu Si has already told Zhou Chang to set up the intelligence system of Dazheng Security from now on, but due to the lack of personnel, the current intelligence system has not made much progress.

Speaking of Zhou Chang, he also had to explain the information about the task that Liu Si gave him to snatch Angola's diamond, gold and silver mineral resources, such as the Catoca kimberlite mining area located 35 kilometers south of Saurimo, the largest open-pit diamond mine in Angola, which was put into operation in 1997 and is the fourth largest kimberlite mine in the world. It is estimated that 60 million carats of diamond will be produced during the opening of the mine, of which 35% will be gem-quality.

To this end, Zhou Chang spent $70 million to purchase a variety of heavy and light weapons, including 100 modified personnel carriers and supply vehicles, two armored vehicles, two light tanks, a medium tank, as well as heavy machine guns, light machine guns, submachine guns, assault rifles and countless other weapons.

There are more than 2,000 personnel, including nearly 50 former professional soldiers from various countries, who operate two armored vehicles, two light tanks, one medium tank, and technical and experienced weapons such as heavy machine guns, and the rest are local Angolan civilians. Originally, more than 3,000 Angolan citizens were recruited, and as long as they could eat enough and have green dollars, the soldiers could be guaranteed.

After about half a year of basic discipline, shooting and other training, its more than 3,000 people were reduced to more than 2,000 people, but more than 2,000 people were able to use. The Katoka diamond mine developed by Israel's Daumonty and Angra's state-owned mining company Shikoku has been in shambles.

Of course, due to the importance of the Katoka diamond mine, there are a lot of troops deployed in Saurim, after all, this is the scope of the Angolan government, and the front line needs, although the number of troops deployed here, reaching more than 2,000 people, almost a regiment of troops, but unfortunately there are no tanks and other weapons, after being killed and wounded by Zhou Chang more than 200 people, he finally took temporary control of Saurim. After looting the funds from the government, banks and other institutions in Saulimu, Zhou Chang led his army to the Katoka diamond mining area.

To tell the truth, if it weren't for Liu Si's chaotic command, Zhou Changcai would not be willing to rush thousands of miles from the coast to South Longda Province, firstly, the existence of the Taizheng Security Regiment was exposed, and secondly, it was not easy to supply from the coastal areas.

After taking the capital of South Lunda Province, Sorimu, he went directly to the Katoka diamond mine, where the defense is not weak, there are more than 500 people, a battalion of troops, the most difficult of which is more than 500 people interspersed with a company of mercenaries, in the Katoka diamond mine Zhouchang suffered heavy losses, as high as nearly 400 losses.

Although a total of more than $50 million was looted, the Katoca diamond mine hastily retreated under the counterattack of the Angolan government army, losing control of the diamond mining area, and the army lost more than 600 people, almost half of it. In this way, he really didn't know whether he had made or lost.

"Basic search techniques?" Sergei Brin muttered, confused.

Hyperlink analysis technology, in today's opinion, this link-based relevance calculation is the norm for search engines, and every SEO person knows it. But thirteen or fourteen years ago, it was undoubtedly a very innovative concept. Even popular search engines on the market do not have the concept of basic search technology.

"The basic search technique is the link-based ranking method of the information retrieval system." Madrid looked at the puzzled expressions of the two and smiled.

"A link-based ranking method for information retrieval systems?" Larry Page and Sergey Brin were very thoughtful, but they couldn't figure out what the hell the hell was the information retrieval system's link-based ranking method!

"Mr. Ma, can you tell us about it?" Sergei Brin, a technoman, has a lot of words today, but he can't resist the curiosity in his heart.

Madrid suddenly sat down on the sofa, smiled very secretly, and said: "The basic search technology is our research results, if you two are interested in joining us, you will naturally be able to know the research results of the basic search technology!" ”

"What does Mr. Ma need us to do?" Larry Page doesn't mind joining a faction, he just needs to know the obligations and disadvantages of joining it.

"The two of you go and register a web search technology company, and our organization will then arrange for someone to inject you with $10 million, of which you can get a total of 15% of the shares." Madrid smiled and said his own conditions, a picture of what you earned.

In this way, Larry Page and Sergey Brin can be regarded as pie-in-the-sky and get $1.5 million, if you don't look at the achievements of the two in later generations, they are indeed cheaper. Liu Si is willing to pay such a big price, mainly because he hopes to really win the hearts of the two guys.

"That's the only way?" Larry Page and Sergey Brin both looked disbelieving and looked very depressed in Madrid, is there a proverb in the United States that pie does not fall from the sky?

"Our organization only wants to make money, and you are our partners."

"If that's all there is to it, we'd like to join you." Larry Page thought for a moment before deciding.

Successful people are good at seizing opportunities, no matter who says it, it is not unreasonable.

Brin listened to Larry's decision, and couldn't wait to know: "Mr. Ma, can you tell us about basic search techniques now?" ”

Madrid looked embarrassed, and after making a big decision, he said: "Originally, the basic search technology should be given to you after the completion of our cooperation agreement." Now, I have decided to believe in your qualities, and I will give you basic search techniques. ”

"Basic search technology, a search engine technology used to retrieve documents related to indexing documents based on queries pointed to by hyperlinks. Its indexer traverses the hypertext database and looks for hypertext information including the address of the document to which the hyperlink points and the anchor text of each hyperlink. The hypertext information is stored in an inverted index file, which can also be used to calculate the link vector for a specific document pointed to by each hyperlink. When entering a query, the search engine finds a vector of all documents in the anchor text that contains the query term. In addition, the query vector is calculated, and then the dot product of the query vector and the link vector for each document is calculated. The sum of the correlation dot product for a particular document determines the relevance ranking of each document. ”

"The basic search technology is the hyperlink file retrieval system and method, which is a link-based ranking method that is different from the traditional information retrieval system. In addition to indexing pages, this system also builds a thesaurus of links that record some relevant information about the link anchor text, such as which keywords are included in the anchor text, the index of the pages that sent the link, the total number of links containing specific anchor text, and which pages the links containing specific keywords point to. The thesaurus contains not only keyword archetypes, but also other derived keywords from the same stem. ”

"Based on this link data, especially the anchor text, the link-based file relevance is calculated. When users search, the resulting link-based relevance is combined with traditional relevance based on keyword matching to get more accurate rankings. ”

"Mr. Ma, you guys are really geniuses who come up with such brilliant ideas." Sergey really admired the talent who could come up with such forward-looking ideas.

"My boss asked me to tell you that he can give you the greatest freedom, but he has one request: to develop a search engine based on a hyperlink file retrieval system and method as quickly as possible." "Of course, don't be afraid of not having funds, our organization will arrange for you to do everything related to financing," Madrid said. ”

"Mr. Ma, we don't have the funds to register the company, I don't know if we can advance $100,000 to help us register the company." Larry is still relatively delicate in dealing with people, otherwise he would not have been able to thrive in the talent-rich Stanford.

"Now I'll give you $10 million, and when our lawyer comes tomorrow, you can register with the state government!" Madrid took out a stack of blank checks from the inner pocket of his suit, picked up a pen and filled it out, "You should pay attention to two points when registering a company, one is that I want to fill in clearly in terms of share shares, it is Liu's Capital that invests in you, and this information will be explained by the lawyer tomorrow; The second is that whether you have the name of the company in mind or not, my boss has already decided on it, and it will be called - Google! ”

"Understood, Mr. Ma."

"Get this check!" Madrid stood up and handed over the filled check, then handed over a postcard, "If it's all right, I'll go." If something can't be solved in the future, just call this phone number. ”

"Goodbye! Mr. Ma. ”

"Goodbye."

When Madrid was gone, Larry Page and Sergey Brin looked at each other incredulously. Especially looking at the check with $10 million written on it in Larry's hand, the two were even more excited. Because the family of the two is not simple, they are not poor ghosts who have never seen the market, and they have already judged the authenticity of the check.
