Searching for relevant English literature is an important step in academic research and thesis writing. Here are some quick ways to find relevant English documents:

1. Use academic search engines: academic search engines such as GoogleScholar, PubMed and IEEEXplore can help you find relevant English documents. These search engines usually provide keyword search function, and you can enter keywords related to your research topic.

2. Use academic databases: Many universities and research institutions subscribe to academic databases, such as WebofScience, Scopus, JSTOR, etc. These databases contain a large number of academic journals, conference papers and dissertations. You can search and obtain relevant English literature through these databases.

3. Read references: In the English literature you find, there are usually some references listed. This method is called "reference tracking".

4. Use academic social networks: Academic social networks such as ResearchGate and Academia.edu can help you establish contact with other researchers and get their research results. You can search relevant English literature on these platforms and communicate with the authors.

5. Attend academic conferences and seminars: Attending academic conferences and seminars allows you to communicate face-to-face with other researchers and learn about the latest research progress. At conferences and seminars, you can ask other researchers questions and get English literature recommended by them.
