But I am to this day quite dissatisfied with any Google alternative, as they all either lack boolean search capabilities, filters for search results (e. g. by site or by image size) or a combination of both.
Same for all the other alternatives I’ve tried to use. I am honestly wondering how people are able to find anything with, for example, Bing or DuckDuckGo …
Are you only doing simple searches, like “nearby restaurant”? How do you search for something that has multiple valid names (OR) and you want to limit search results to before:2015, if the search engine doesn’t support search operators?
