    ***TLDR; It is safer to force an 'all' research***
        IlCorsaroNero's categories are very specific
        qBittorrent does not provide enough categories to implement a good filtering.
        For example, qBittorrent provides only a generic 'games' category meanwhile the website uses: pc, xbox and so on
