Some resources will
allow you to combine your keywords in different ways. One of those ways is to
combine terms using the word “or”.

You use OR to combine
words that mean the same thing. Authors may refer to the same thing using
different terminology. To ensure that your search retrieves all the items
relevant you should include a range of terms.
For example someone may
refer to “kidney disease” but another person may call it “renal disease”. Your
search needs to return both sets of information, so you should search for items
that contain either kidney OR renal disease.
Here’s a short animation
from HEE explaining the use of OR:
