From Topic to Full Text - Searching Subject Databases

Do you have a topic for a term paper / Bachelor's thesis / Master's thesis / research paper etc., and have you not found relevant and appropriate literature yet? Was your last search confusing and did it take a lot of time?
Have you already searched databases but found too few / too many / irrelevant hits?

If you responded "yes" to any of these questions, this is the right course for you.
