Only 619. Hmm
I have to say, I never use the second page of any search engine. When I am searching for an obscure site or something, I use other methods to find the link to the website I am looking for. We all know that search engines hide relevant info if it does not meet a quota of popularity. In other words, you could search the exact thing you want, but if it is not popular, it will not show up at the first page for sure, and sometimes not even the other pages. The fact that search engines are not the source of limitless results is pretty eye opening though.
I tried the internet archive instead. It is mostly in english, so many important sources are likely not present, but it produced 30 thousand results! I also sorted by articles and texts only, to make it practical. Since internet archive is painfully slow, I didn't go very deep, but there were way more results. Some things were blocked by account walls, but even then, there were way more unlocked than show up in all of google. Crazy
Zlibrary ends mysteriously at exactly 500 results, even though it says 500 plus. Making it obvious that they are hiding results for some reason. Interestingly, you can select a single year of publication, and you still get only 500 results, so there is obviously a large pool they are accessing, but they don't let you look at it all at once for some reason.
Libgen has better access to zlibrary's library ironically, and is shows 2090 results, all of which are accessible easily through zlibrary.
If you want scientific sources or books, using a combination of the previous things, researchgate, google scholar/sci hub (with extension) can get you basically any worthwhile research. (Of course I'm excluding schizo science self publishing). Sci hub claims 88,485,382 articles, while research gate claims 135 million. for google scholar, there are general topics you can choose from, and climate change shows 900 390 results. The page menu breaks after page 30, so I don't know how many results you can actually access. Its a fuck ton though, and there is no way you can read them all. However,
The general searches for these sites is restricted like google and you have to know what the study is called exactly to find it. The search option for researchgate for climate change stops at only 10 pages! On google scholar(sci hubs search engine), past page 98, even though there are 100 pages, you get a "server error" and while I don't know how much there are, in 98 pages, there is no way in hell it is 4410000 results as google claims. I think this is because actual academics have inside info, and they know what the study is called, so the general search is useless for them. This makes information only accessable to the academics.
The key here is that although there are archive sites that have info, they hide search results, so you have to know exactly what it is called to find it, but if it is hidden across al search resources,
you cannot know what it is called and you can never access it unless you have inside info. Maybe because of site loading times, or something? anyway super fucked.
