Mark idea as hidden or unlisted so it doesn't show up in search results
We are still trying to figure out the best approach to handling duplicate ideas. At the moment, we are responding to the poster with the original idea they should vote on, setting to a status of "Duplicate" and closing the topic. Unfortunately, they still show up in search results and search suggest. This clutters the user experience.
Ideally, I'd like to mark these as "unlisted" so they still exist and are accessible by directly hitting the URL from for example an email, but they do not show up in search results or any other browse interfaces. This is similar to the YouTube unlisted video concept.
