Is there anyway to search for specific file types?

[Car-Role]

I'd like to search only for switch games so, .nsp files only and regret any others. Is this possible?

Not natively since the system only receives data from the indexers (which are torrents or nzb)
For this to be done, we would need metadata with the content of the file which I'm not sure is possible but would need to be investigated
What you can do is use categories from the indexers if they offer this kind of sub cat
