Specific Filtering on YouTube
If you select the YouTube tab, you will have access to the option to filter by number of channel subscribers, which allows you to filter by the number of subscribers to a channel. With this option, you can select to see channels with a minimum or maximum number of subscribers. For example, it is possible to show only the channels with more than 100 subscribers, less than 1000 subscribers or an amount of subscribers within a certain number.
You will also have access to the option to filter by Type, which allows you to filter results by Video, to show only videos posted to YouTube, or by Comments made on YouTube videos. If no type is selected, everything, both videos and comments, will be shown in the results.
