You can use WOS and other document retrieval engines to retrieve English documents. WOS is my most commonly used database. Its advantage is that the retrieval results of documents are more comprehensive and rigorous, but its disadvantage is that the database update is not timely enough and there are still some defects. Pubmed's database is updated quickly, but advanced retrieval is not very easy to use.

In addition, it can also be searched by author's way, institution (institution author or institution where the author works) index, patent literature retrieval system with patentee's index, etc.
