Precisely what I wanted to ask as well. I only of yandex which gives really good results like old google, but I'd rather have alternatives in case when yandex fails.

The general search engines that I know of are (ordered from best to worst): - yandex - ddg - google

Literally any search engine, regardless of affiliation, is welcome as long as it returns google-grade results (old google ofc) for more than half its searches.
