Ideally, the world needs more internet search engines - as of now only Google, Bing, Yandex, Baidu come to my mind. And various initiatives like Cuil, Wikia Search, etc failed or good ones like Exalead (EU sponsored Google competitor, bought by Dasault), Blecko (bought by IBM for Watson) got bought and vanished for general public but are still active for internal company purposes.
And why do we need more web search engines? Because of the filter bubble, censorship and privacy concerns, etc. - it's never good to have to deal with a mono- or duo-poly (which is already reality, as in most countries on 1-2 of them return really good search results, and the others are barely useable for local native language search phrases).
It seems to be just lumping results together by language without putting enough weight on location.
Funny thing is, I have just the opposite issue with google. While traveling, it constantly tries to force me to use the local version even if I don't want to (redirecting from google.com etc.) which puts more weight on local results.
I don't think they use IPs to geolocate, so I find myself using yelp (or sometimes tripadvisor/citysearch) for local results.
Maybe a geolocating custom search / instant answer box (that can be opt-in/out) would help. It is one step down the slippery slope of search bubbling/tracking, but maybe that isn't the end of the world -- it could be done by town or something.
While my countries flag was displayed next to the search bar it was set to "All results" in the menu, so I have to explicitly enable the region filter by flipping the switch next to it.
Let's say everybody stops using Google right now and starts using DDG with its anonymous, proxied queries to Bing. How does this in any way improve search results? You could maybe argue that heavy direct use of bing.com would give Microsoft some useful training data. But none of that changes the fact that Bing's crawlers aren't that good, and neither is its search engine.
