Have you set up shortcuts / redirects for some of your pages in Episerver that you are now seeing duplicate results in your site search? One is the correct page and the other is the shortcut page?
There are several approaches to exclude shortcuts / redirects from your search results:
Do not send these pages that are shortcuts to the Episerver Find Index. By doing this, you won’t need to apply any filters when making queries to the Find index.
Send these pages to the Find index, but ensure you apply a filter on your queries to Find to exclude them on the frontend.

Find your Search Initialization Module class (or create one if you don’t have any)
Tell Epi Find to only index pages that have not been set up with shortcuts by adding the below convention:
