Personalized search engine

Yandex has the opportunity - “advanced search”. Where it is possible, by setting various parameters, to focus your request in order to increase your chances of success in finding what is required. But!

I used it, twisted the settings, found what I needed, left - and! everything needs to be done again if you come back. Neither use it again, nor show people. Plus, however, essential: the entire base of Yandex.

On the other hand, there is such a service “personal search engine from Novoteka”. Where it is possible to set pens sites, among which only will be searched. The chip: this personal search engine can be given to anyone who wants to use it, it is a kind of independent phenomenon. Difficulties: firstly, this is still beta, and secondly, the required sites should already be known.

A natural, dreamy desire arises: but Yandex would allow, the customized “advanced search” page, to present to me in the form of my personal search engine for general use. And if you go further, it would be a good opportunity to add your own ranking fields and use such a personal Yandex!

I’m talking about Yandex only because ... because I’m talking :)
