added user selectable search domain and updated docker files

[jkumeboshi]

user can select the google search domain in setting.
The domain is checked against a configurable list of supported TLDs.

Updated all docker files to include all changes in config/settings

Great changes! If the repository maintainer merges it, I'll update the docker image on Docker Hub with your customizations included.

Whats the point of the user changing the domain?

The host will complete the request anyway, and the domain has nothing to do with language preferences.

[jkumeboshi]

That's a good question.
Actually from my tests I saw that Google behavior changes slightly depending on various parameters:

1. The web site domain
2. The language you choose
3. Your location (Actual or GeoIP)
4. Additionaly there is the ability to filter results by language

That happens at least accessing Google normally using the browser.
for point 1, 2, and 4 we can allow the user to have his specific settings, to mimic his preferred Google expected behavior.

I have done some tests and I couldn't find a difference in the results when I compared .hu and .com.
So I don't think this has any usecase.

Maybe different TLDs don't have any effect; but, like on SearX, this option 4 would be interesting. 😺

@r1klz you mean the user may change result's language in the search results page?

Something similar to DDG that has quick settings for language, safe search and search dates too:

Exactly, @jkumeboshi.
Sometimes I search websites/things in my native language and the results I need doesn't appear. So I think this option is very good to be implemented...
However, depending on the instance (the country where it's hosted), it will return some results based in that country. But if it does not have a instance in your country? Know what I mean?

You need to solve branch conflicts!

I will probably implement in the quick langauge change when I have time.
