engine.

When initing engines a "SearxEngineResponseException" is logged very verbose,
including full traceback information:

For SearxEngineResponseException this is not needed. Those types of exceptions
can be a normal use case. E.g. for CAPTCHA errors like shown in the example
above. It should be enough to log a warning for such issues:
WARNING:searx.engines:yggtorrent engine: Fail to initialize // Cloudflare CAPTCHA, suspended_time=1296000

The old xpath configuration for google scholar did not work and is replaced by a

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.
At the moment videos without a description are not shown - setting
default content to "" fixes this.
Another current bug is that thumbnails are not displayed. This is caused
by a double slash in the url. For this every trailing slash is now
stripped (for backwards compatibility) and the API response is correctly
parsed.
* searx understand "!ddg !g time" as : send "!g time" to DDG
* !g a DDG bang for Google: DDG return a HTTP redirect to Google
This commit adds a the allows_redirect param not to follow HTTP redirect.
The DDG engine returns a empty result as before without HTTP redirect.
on some queries (like an IT error message), wikipedia returns an HTTP error 400.
this commit returns an empty result instead of showing an error to the user.
Some JSON API returns HTML in either in the HTML or the content.
This commit adds two new parameters to the json_engine:
content_html_to_text and title_html_to_text, False by default.
If True, then the searx.utils.html_to_text removes the HTML tags.
Update crossref, openairedatasets and openairepublications engines
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.

The 'video.html' template from the 'oscar' design supports replacement
for *author* and *length*. Google-videos does not have an author, alternatively
the publisher info from is used for the *author*.
Hint: these replacements are not supported by the 'simple' design.

First the method searx call the get_params method.
If the return value is not None, then the searx call the method search.
check HTTP response:
* detect some comme CAPTCHA challenge (no solving). In this case the engine is suspended for long a time.
* otherwise raise HTTPError as before
the check is done in poolrequests.py (was before in search.py).
update qwant, wikipedia, wikidata to use raise_for_httperror instead of raise_for_status
before commit 58d72f2, category was not set in xpath.py,
so searx/engines/__init__py was setting the category to ['general']
the commit 58d72f2 set the category to [] which is not replaced by searx/engines/__init__.py
consequence: the mojeek engine is hidden in the preferences.
this commit revert the xpath.py change.
close#2368
Add a new parameter "raise_for_status", set by default to True.
When True, any HTTP status code >= 300 raise an exception ( #2332 )
When False, the engine can manage the HTTP status code by itself.

recoll is a local search engine based on Xapian:
http://www.lesbonscomptes.com/recoll/
By itself recoll does not offer web or API access,
this can be achieved using recoll-webui:
https://framagit.org/medoc92/recollwebui.git
This engine uses a custom 'files' result template
set `base_url` to the location where recoll-webui can be reached
set `dl_prefix` to a location where the file hierarchy as indexed by recoll can be reached
set `search_dir` to the part of the indexed file hierarchy to be searched, use an empty string to search the entire search domain
Devian's request and response forms has been changed.
- fixed title
- fixed time_range_dict to 'popular-*-***'
- use image from <noscript> if exists
- drop obsolete "http to https, remove domain sharding"
- use query URL https://www.deviantart.com/search/deviations?page=5&q=foo
- add searx/engines/deviantart.py to pylint check (test.pylint)

use

so it is possible to easily remove all unused import using autoflake:
autoflake --in-place --recursive --remove-all-unused-imports searx tests
Xpath engine and results template changed to account for the fact that
archive.org doesn't cache .onions, though some onion engines migth have
their own cache.
Disabled by default. Can be enabled by setting the SOCKS proxies to
wherever Tor is listening and setting using_tor_proxy as True.
Requires Tor and updating packages.
To avoid manually adding the timeout on each engine, you can set
extra_proxy_timeout to account for Tor's (or whatever proxy used) extra
time.
- remove paging support: a "vqd" parameter is required between each request. This parameter is uniq for each request
- update the URL (no redirect), use the POST method
- language support: works if there is no more than request per minute, otherwise it is ignored !
Since 1. October 2020 google has changed the 'class' attribute of the HTML

A new "base" engine called command is introduced. It is the foundation for all command line engines for now.
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.
