The new url parameter "timeout_limit" set timeout limit defined in second.
Example "timeout_limit=1.5" means the timeout limit is 1.5 seconds.
In addition, the query can start with <[number] to set the timeout limit.
For number between 0 and 99, the unit is the second :
Example: "<30 searx" means the timeout limit is 3 seconds
For number above 100, the unit is the millisecond:
Example: "<850 searx" means the timeout is 850 milliseconds.
In addition, there is a new optional setting: outgoing.max_request_timeout.
If not set, the user timeout can't go above searx configuration (as before: the max timeout of selected engine for a query).
If the value is set, the user can set a timeout between 0 and max_request_timeout using
<[number] or timeout_limit query parameter.

Updated version of PR #1413 from @isj-privacore
Server Timing specification: https://www.w3.org/TR/server-timing/
In the browser Dev Tools, focus on the main request, there are the responses per engine in the Timing tab.
languages.py can change, so users may query on a language that is not
on the list anymore, even if it is still recognized by a few engines.
also made no and nb the same because they seem to return the same,
though most engines will only support one or the other.
The timeouts in settings.yml is about the total time (not only the HTTP request but also the prepare the request and parsing the response)
It was more or less the case before since the threaded_requests function ignores the thread after the timeout even the HTTP request is ended.
New / changed stats :
* page_load_time : record the HTTP request time
* page_load_count: the number of HTTP request
* engine_time : the execution total time of an engine
* engine_time_count : the number of "engine_time" measure
The avg response times in the preferences are the engine response time (engine_load_time / engine_load_count)
To sum up :
* Search.search() filters the engines that can't process the request
* Search.search() call search_multiple_requests function
* search_multiple_requests creates one thread per engine, each thread runs the search_one_request function
* search_one_request calls the request function, make the HTTP request, calls the response function, extends the result_container
* search_multiple_requests waits for the the thread to finish (or timeout)
- pre_search(request, search)
- post_search(request, search)
- on_result(request, search, result)
with
- request is the Flask request
- search a searx.Search instance
- result a searx result as usual
Purposes :
- isolate the plugins calls
- distinction between parsing the web request and running the search (Search class). To be able to test code easily, to run searx code outside a web server, to filter the search query parameters with plugins more easily, etc...
Details :
- request.request_data contains request.form or request.args (initialize inside pre_request() function)
- Query class is renamed RawTextQuery
- SearchQuery class defines all search parameters
- get_search_query_from_webapp create a SearchQuery instance (basically the previous Search.__init__ code)
- Search class and SearchWithPlugins class takes a SearchQuery instance as class constructor parameter
- SearchWithPlugins class inherites from Search class, and run plugins
- A dedicated function search_with_plugins executes plugins to have a well define locals() (which is used by the plugins code).
- All plugins code is executed inside the try...except block (webapp.py, index function)
- advanced_search HTTP parameter value stays in webapp.py (it is only part of UI)
- multiple calls to result_container.get_ordered_results() doesn't compute the order multiple time (note : this method was call only once before)
- paging value is stored in the result_container class (compute in the extend method)
- test about engine.suspend_end_time is done during search method call (instead of __init__)
- check that the format parameter value is one of these : html, rss, json, rss (before the html value was assumed but some text formatting wasn't not done)
