* Yandex: 70.7%
* Google: 23.3%
China: * Baidu: 59.3%
* Other domestic engines: "smaller shares"
* Bing: 13.6%
South Korea: * Naver: 59.8%
* Google: 35.4%
Japan:
* Google: 76.2%
* Yahoo! Japan: 15.8% * Too many crawlers (see note below re crawlers)
* Crawlers not being friendly
* Improper use of the crawled data
* Not getting compensated for their content
Why not the index? The index, to me, is where a bunch of the "magic" happens and where individual companies could differentiate themselves from everyone else. * Do they not have enough crawled data?
* Their index isn't very good?
* Their searching their index isn't good
* The way they present the data is bad?
* Google is too entrenched?
* Combination of the above?
There are several entities intending to crawl all / large portions of the Internet: Baidu, Bing, Brave, Google, DuckDuckGo, Gigablast, Mojeek, Sogou and Yandex [1]. That does not include any of the smaller entities, research projects, etc.

The abstract: “ It is proposed that happiness be classified as a psychiatric disorder and be included in future editions of the major diagnostic manuals under the new name: major affective disorder, pleasant type. In a review of the relevant literature it is shown that happiness is statistically abnormal, consists of a discrete cluster of symptoms, is associated with a range of cognitive abnormalities, and probably reflects the abnormal functioning of the central nervous system. One possible objection to this proposal remains--that happiness is not negatively valued. However, this objection is dismissed as scientifically irrelevant.”
