AT the moment, search terms are divided into audio, video, images, text, others etc. These are but very wide terms, especially for users who want to quickly search  their favourite movies or TV series. I request developer provide better search terms like movies, tv series, anime, mangas etc.. This will help to narrow down search more and help in targeted quick searching.

technically what you are searching for are filenames, the buttons select which file type (audio files, video files, etc) ...
sorting by 'genre' for example depends on how someone else has their files named and sorted.. and everyone organizes things differently..

this request is not really possible as it is not how 'search' is supposed to work.
