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

You use AND to combine different concepts that mean different things. This helps you to narrow your search helping it to be more specific.
For example you may be

for “kidney disease” AND hypertension you are narrowing your search about
kidney disease to only include items which also include the search term
hypertension.
Here’s a short animation
