academic search engines have become the number one resource to turn to in order to find research papers and other scholarly sources. While classic academic databases like Web of Science and Scopus are locked behind pay walls, Google Scholar and others can be accessed free of charge. In order to help you get your research done fast, I suggest you the following list of academic search engines:
1. Google Scholar
2. Microsoft Academic
3. BASE
4. CORE
5. Science.gov
6. Semantic Scholar
7. Baidu Scholar
For more details, regarding their pros and cons, please see the source at: https://paperpile.com/g/academic-search-engines/
And also I suggest you to have a look at the interesting web site below, regarding the Trusted (And Free) Search Engines For Scientific and Academic Research at:
In chemistry most universal and reliable are Reaxys and SciFinder; both are highly specialized and paid services. Google and its derivatives are useful, but with general internet search engines you never know if you don't miss something important.
Yet if we type "technical papers" in google, It will show that this kind of publications differ to a certain limit from regular non technical papers that can be browsed using all your mentioned engines
Dear Gabris Mahamid, Such a database aggregated and sorted at this stage is being developed. It has not been tested and therefore cannot be seen. The development is of large companies such as: Web of Science, Scopus, Google Scholar and Google Academia, Microsoft Academic, Semantic Scholar and others. There is only a partial finding at this stage of these data companies on specific topics in specific areas. Wishing you success in research. Emil Yankov
