We're using custom Bing search ( https://www.customsearch.ai/ ) as a custom search solution in our website. Initially we were having some pdfs and those are now removed from the server but when we search those pdfs, related links are still showing on search result page. When we click those links, we're getting 404 page which is expected because now those pdfs doesn't exist.
I guess somehow links are indexed and remains somewhere in custom Bing search.
Is there any process to clear orphan links from search result page? Is there any configuration that we can set up so that going forward if we remove pdfs from the server, related links are also removed?
