Mind maps can be an excellent place to start a research project.
Start with a simple brainstorm session with your general topic in the middle, and start expanding concepts in other bubbles.
You'll quickly start to see the many ways you can approach a subject, and how to connect concepts.
Use the concepts you come up with and use them as search terms when you are ready to transfer your research to the second step: using a library search tool or a database.
