Show user CAPTCHA when asked by Google

[gabrc52]

Is your feature request related to a problem? Please describe.

When searching from Google through searx, Google sometimes decides it's too many requests or if it determines that they're suspicious or robot-looking, it can display a CAPTHCA, which makes searx unable to return results.

A single user can trigger a CAPTCHA, I know since I have gotten a CAPTCHA on my normal IP address by typing queries that include parameters like site: on my keyboard.

Describe the solution you'd like

Since searx users are humans, searx could forward the CAPTCHA to them in order to complete the search. I wouldn't mind being asked to tell searx which of the pictures are cars, so it can reply that to Google.

Describe alternatives you've considered

From searching open issues, #2439 proposes falling back to another proxy, but these may be limited -- what if all of the proxies display a CAPTCHA? Many instances may have only one IP address available, which may trigger the CAPTCHA.

Additional context

Not possible, I explained why here: #729 (comment)

@unixfox while it may not be possible to display this with web technologies, I can think of ways to do it:

• Screen mirroring a browser instance (something like VNC)
• Also using a browser instance on the server: Parse the contents of the CAPTCHA itself, and show them to the user so the user can click on the image of a car or whatever the CAPTCHA asks for. Then the server returns to the CAPTCHA what the user selected.

yes but including a whole browser into searx will increase the size of the whole searx installation by A LOT. that's why we won't do that.
