Search expansion
What search expansion is
Sometimes, we'll automatically include terms in your search when we think it will help you find what you're looking for. For example, if you search for "audiobook" we'll include items from the audiobook category, even if they don't have the word audiobook in the title. This is why, for certain searches, additional items appear in the search results even though not all the keywords you entered are in the title.
Note: This feature is available in the US, Canada, the U.K., and Germany.
While you can't turn off the search expansion feature, it will automatically turn off if you use any search operators (Boolean logic).
How search expansion works
There are 3 types of automatic search expansions that we use to give you the best results for your search queries.
