How do I filter results by keyword

Hi,
as far as I know there is no real filtering possible. But you can use certain (advanced) search parameters to make a search more precise.

I’ve added a new parameter, called ‘filter’, in the current plugin version 1.5.0. There you can add such search parameters (or actually any additional search terms you like) that will always be added to the YouTube search.

So to stick with your example, by now adding [relatedYouTubeVideos … filter=”intitle:official -intitle:cover -intitle:lyrics”] you might only get the official music video, no cover version and none of those videos that only show the lyrics as a slideshow.
