Yandex Says Nyet to Google and Da to Nasdaq

Arkady Volozh, the founder and chief executive officer of Russia's dominant search engine, Yandex, seems comfortable being the outsider. He's one of Moscow's wealthiest people yet still drives his own car, a Volvo SUV, in a city of chauffeured Bentleys and Maybachs. Despite Russia's penchant for nepotism, for years Volozh refused to hire his oldest son and insisted he find a job on his own. He "is not very ostentatious or grandiose at all, which is why he wears well," says Esther Dyson, a venture capitalist and Yandex board member.

He may be tempted to live a little larger after May 24, when Yandex is expected to raise around $1 billion in an initial public offering on Nasdaq ( NDAQ ). Most of Russia's successful companies are those that dig—for oil, nickel, aluminum. Others are tainted by accusations of corruption or intellectual-property theft. Yandex seems to be an exception: a homegrown market leader that leveraged Russia's math and engineering talent in pursuit of technological breakthroughs. According to research group LiveInternet, its search engine now accounts for 64 percent of the Russian market to Google's 23 percent, and Yandex is hinting at ambitions abroad. For foreign investors, the question will be whether the Kremlin leaves the company alone.

Volozh and his high school friend, Ilya Segalovich, started working on search in the early 1990s. Their Internet search engine went live in 1997, and Yandex, which stands for "yet another indexer," became an independent company in 2000. Revenue has doubled every year since, and in the first quarter of this year, Yandex brought in $137 million, almost entirely from ads, according to its prospectus.

Part of the explanation for Yandex's success is first-mover advantage. Google ( GOOG ) didn't open a Russian office until 2005. Volozh and Segalovich began work on their indexing technology before Sergey Brin and Larry Page had even met, and they added maps, news search, and Web mail to Yandex's offerings years before Google did. Yandex "has outpaced the big, brand-name Internet companies," says Web pioneer Anton Nossik, who founded popular Russian news sites. It "did this by thinking about what was needed here, in the domestic market, and not what was already available."

Being native Russian speakers helps. Yandex's algorithm accounts for the intricacies of Russian grammar, where the same word can have dozens of different endings depending on its place in a sentence.

College Textbook Search Engine List | High School Math Textbooks

You can use a college textbook search engine to help you to find the textbook that you need for your next class. One of the most shocking aspects of college occurs once you enter the school’s bookstore and you discover just how expensive the actual books are for the courses. What you may find is that some of these books are nearly as expensive as the courses you are taking. Further, they change so frequently that you may find yourself unable to get the good price you are after.

However, you can use a search engine to help you. If you do use a college textbook search engine, you do need to keep in mind that some of these programs provide you with the wrong book. There are some very specific bits of information you need to look for before you purchase the book in this way.

•    The title of the book needs to be the same •    Look at the edition, which changes as often as each year

If you do consider some of the older textbooks, you may want to consider what makes them different before you buy an older but less expensive textbook. In general, these newer editions can continue new and updated information. However, you can ask your professor if the previous edition contains the information that you need or if it is not an acceptable solution.

A college textbook search engine will reveal thousands of books on the topic you have selected, but you may find yourself struggling to learn the ins and outs of every book. You can save money if you take the time to consider all of the available books, though.
