Information source from EI Academic Conference Center : EI search query
The most authoritative way to search for a paper retrieved by EI is to directly enter the EI database, enter the English title of the article, and click "serach". If you can find the result (usually there is only one result, because the title of the paper is the only one), it means that the paper has entered the EI database. If there is no search result, it proves that the paper has not entered the EI database.
This is the official website of the EI database: http://www.engineeringvillage.com

pay attention: To directly access this EI database website, you need to log in, so you cannot inquire papers. Only some universities that have purchased the EI database can log in to the official website of the EI database to search for papers through the school intranet. If you are a college unit, first ask if your school has purchased an EI database, if not, ask your friends who work in other colleges and universities.
