Searching by theme / tag (e.g Christmas)

[King Mustard]

I want to search for Christmas-related content.

When I search for "Christmas", Jellyfin is only display titles that:

• contain the word (e.g "Christmas Evil")
  
• contain the word in a person's name (e.g "Eric Christmas").
  

For example, Spirited nor It's a Wonderful Life appear in the results.

Is this resolvable, somehow?
