This patch fixes some quirks and issues related to the engines and the network. Each engine has its own network and this network was broken for the following engines[1]: - archlinux - bing - dailymotion - duckduckgo - google - peertube - startpage - wikipedia Since the files have been touched anyway, the type annotaions of the engine modules has also been completed so that error messages from the type checker are no longer reported. Related and (partial) fixed issue: - [1] https://github.com/searxng/searxng/issues/762#issuecomment-1605323861 - [2] https://github.com/searxng/searxng/issues/2513 - [3] https://github.com/searxng/searxng/issues/2515 Signed-off-by: Markus Heiser <markus.heiser@darmarit.de>
