Graphic listing several concepts leading to one set of results
For example:

  • Your first search for your first concept may include all your different keywords and phrases for kidney disease, using OR to combine them.
  • Your next search might be for your second concept hypertension – you’ll need to identify all the relevant terms for hypertension and combine them using OR.
  • You can then combine both these concepts using AND for example as search1 AND search2.

You can learn more about how to combine searches by completing our etutorial Develop Your Search Skills
