It is strange that on Habré was not yet this news. Yandex launched a few days ago testing its new search algorithm called "Snezhinsk". The new Yandex agglossment includes more than 1000 search parameters for one document. View the presentation (PDF in English). You can test the algorithm itself on buki.yandex.ru .
Yandex gives the names of algorithms on the principle of the game “Cities”, when each next city begins with the last letter of the previous one: Magadan - Nakhodka - Arzamas - Snezhinsk. ')
PS For me, this is doubly interesting news, since I grew up in Snezhinsk.
