Looking for basic - or background - information on a topic is best done in textbooks or other resources that compile the known and standard information into a single resource. For example, if you need to know more about what Graves' disease is or what the usuall treatment is, an article search probably will not help as much looking it up in a textbook (either print or our online books) or some of our synthesized resources (Medscape, UptoDate).
Sythesized Resources
These resources are more clinically focused. Their coverage of basic topics may not be as fully explained so you might need to use a textbook to round-out your understanding.
The Big Tomes
The Handbooks
In most cases, when searching in these resources one word or phrase is better than a long question or multiple concepts.
