Mpsa
web_production: 513
Weight: 0.093045433292429 Evaluates the minimum distance between the pairs of words of the request, taking into account the remoteness of the pair from the beginning of the document (Minimal Pair Size with Attenuation). Steles are understood to mean all consistent bigrams of the words of the request. Thus, the number of vapor is equal to the number of words in a request reduced by 1. Accordingly, the factor makes sense for requests consisting of more than one word. (Http://wiki.yandex-team.ru/jandekspoisk/kachestvopoiska/obshayaformula/ Tekushhiekomponenty/MPSA MPSA))

For removal from the beginning of the document, we finish the model.
