It scares me actually, when trying a search I got this:
поиск временно недоступен. пожалуйста, используйте DOI или прямые ссылки
search temporarily unavailable, please use DOI or direct links
If you're using Google chrome, you can install Sci-Hub extension to use search.
To do this:
Download the extension and unpack it. You get the "Sci-Hub" folder with code.
Open Chrome and navigate to chrome://extensions, or just open the menu -> settings -> extensions.
Check the developer mode in upper right.[...]
It's the message that shows up when you try searching. It says that "search temporarily unavailable, please use DOI or direct links" and then under that "If you're using Google chrome, you can install Sci-Hub extension to use search", with instructions. I've installed it in the past and it does work, but I was also wary about enabling developer mode and Chrome would nag me on startup each time that it was unsafe so I ended up disabling it. Here's the full text: https://pastebin.com/6RnRJYUa.
You probably just paste DOI codes there like most of us. Originally, sci-hub supported searching for codewords/topics (by using Google Scholar), but then their IPs got banned from Google Scholar and the workaround is to install this extension. It modifies Google Scholar pages so that all links to paywalled articles are replaced with links to sci-hub pdfs of same articles. Google would never approve this extension, so you need to install it in dev-mode.
But again, for most people's usage, it's completely unnecessary. Paste DOI -> get pdf works without any 'extensions' necessary.
