Starting with an Internet search can help you identify scholarly/research articles on bilingualism, but there's an extra step:
1. Look in the online source/article for references to a research study/project. Identify the author, date, and perhaps the source of the article.
2. With that information you can use the sources in the Finding Articles tab to search for that research study/project.
3. Follow the links in the database record to get to the full-text of the journal article.
