Here are the correct search results:
- apples AND oranges: You will get sources that are about both apples and oranges. You won't get sources that are only about apples, or are only about oranges. If you are interested in more than one topic, this is useful to find sources that include both.
- apples OR oranges: You will get sources that are about both apples and oranges as well as sources that are only about apples, or are only about oranges. This is the broadest search type.
- apples NOT oranges: You will get sources that are only about apples. You won't get sources that are about both apples and oranges, or sources that are only about oranges. This is useful to exclude a topic that isn't relevant to your search.
