Problem

When searching for music in Flowtube, search results are not separated into categories such as artists, featured playlists, and podcasts. This makes it difficult to find a specific type of content, especially when results from different categories appear together.

Proposed behavior

Add category filters to Music search so users can narrow results by content type, such as Artists, Featured playlists, and Podcasts. Users should be able to select a category to see matching results and return to all results easily.

Relevant area

Search or browsing

Alternatives considered

Users can currently scroll through the mixed results and look for the type of content they want. This is less convenient than filtering by category.

Privacy, security, and resource impact

None

Additional context

The category filters could appear as tabs or chips near the top of the search results
