How to form a query in a search engine?

Question

Google

I suddenly discovered that neither Yandex nor Google understand my requests. Previously, only Google suffered from this. That is, if my request did not pass autocompletion, then the result will be anything, but not the one that is needed. And it happened a year or two ago. What's up with the search engines? Or is everything now for the sake of advertising and you only need to look for what is advertised?

Answer 1

I form the request by increasing degree of refinement (probably, you can say so).
buy a computer in
krasnodar kohana write to several databases
, etc.
I don’t know how optimal it is, but it always works fine in any PS :) from general to particular.
