The `url_for` function in the template context is not the one from Flask, it is
the one from `webapp`. The `webapp.url_for_theme` is different from its
namesake of Flask and has it quirks, when called with argument `_external=True`.
The `webapp.url_for_theme` can't handle absolute URLs since it pokes a leading
'/', here is the snippet of the old code::
url = url_for(endpoint, **values)
if settings['server']['base_url']:
if url.startswith('/'):
url = url[1:]
url = urljoin(settings['server']['base_url'], url)
Next drawback of (Flask's) `_external=True` is, that it will not return the HTTP
scheme when searx (the Flask app) listens on http and is proxied by a https
server.
To get the right scheme `HTTP_X_SCHEME` is needed by Flask (werkzeug). Since
this is not provided in every environment (e.g. behind Apache mod_wsgi or the
HTTP header is not fully set for some other reasons) it is recommended to
get *script_name*, *server* and *scheme* from the configured `base_url`. If
`base_url` is specified, then these values from are given preference over any
Flask's generics.
BTW this patch normalize to use `url_for` in the `opensearch.xml` and drop the
need of `host` and `urljoin` in template's context.

Bing has a list of regions that it supports and some of these regions
may have more than one possible language.
In some cases, like Switzerland, these languages are always shown as
options, so there is no issue. But in other cases, like Andorra, Bing
will only show one language at the time, either the region's default or
the request's language if the latter is supported by that region.
For example, if the HTTP request is in French, Andorra will appear as
fr-AD but if the same page is requested in any other language Andorra
will appear as ca-AD.
This is specially a problem when Bing assumes that the request is in
English because it overrides enough language codes to make several major
languages like Arabic dissappear from the languages.py file.
To avoid that issue, I set the Accept-Language header to a language
that's only supported in one region to hopefully avoid these overrides.

The new version of MetaGer needs to reload the reults (into a iframe) with a

Implementing a dedicated metager-engine for searx makes no sense to me. The
great days of MetaGer seems to be ended. I remember the good old days this
project started in the 90's of the last century. But in the last few years it

the i18n is very poor compared to what searx offers.

Some of our interface locales include uppercase country codes,
which are separated by `_` instead of the more common `-`.
Also, a browser's `Accept-Language` header could be in lowercase.
This commit attempts to normalize those cases so a browser's
language+country codes can better match with our locales.
This solution assumes that our UI locales have nothing more than
language and optionally country. If we ever add a script specific
locale like `zh-Hant-TW` this would have to change to accomodate
that, but the idea would be pretty much the same as this fix.
The language_support variable is set to True by default,
and set to False in only 5 engines.
Except the documentation and the /config URL, this variable is not used.
This commit remove the variable definition in the engines, and
set value according to supported_languages length: False when the length is 0,
True otherwise.

* URL / : the index page displayed the selected or the default category.
* URL / : when the q parameter is set using the URL, the redirect includes the URL query.

This makes it easier to separately handle search and index requests
from a web server or from a reverse proxy.
If a request to index contains a query, a permanent redirect HTTP response
is returned. This should give some level of backwards compatibility

You can use this engine to create your own command line engine.
Add some engines (commented out to make sure no one enables anything accidentally):
* git grep: This engine lets you grep in the searx repo.
* locate: If locate is installed and initialized, you can search on the FS.
* find: You can find files with a specific name from where you started searx.
* pattern search in files: This engine utilizes the command fgrep.
* regex search in files: This engine runs `grep` to find a file based on its contents.
and some other exceptions:
* KeyboardInterrupt
* SystemExit
* RuntimeError
* SystemError
* ImportError: an engine with an unmet dependency will stop everything.
Sending queries through POST, while better for privacy, breaks functionality
with certain extensions (e.g. Firefox containers). Since Firefox does
not send cookies when requesting `/opensearch.xml`, users cannot easily
switch to GET on the client side unless they make a custom search
engine. This commit allows admins to modify the default method on their
side so they can set it to GET if needed.
Sending query params over GET seems to be the only way to be able to
enable autocomplete in the browser. This commit adds the necessary URL
formatting to opensearch.xml. In order to identify queries coming from
the URL bar (rather than an AJAX request), which requires a different
JSON format and MIME type, the request headers are checked for
"X-Requested-With: XMLHttpRequest" which is added by jQuery request.
- enabling HTTPS for sci-hub.tw by default
- making sci-hub the default DOI resolver as it has the largest collection of scientific articles.
- replaced doai.io with dissem.in, as it redirects to this new domain.
