[Enhancement]: implement "Faceted Search"/Multiple filters

[Gru0810]

Describe the feature/enhancement

While looking for an audio book, I came across the website “archive.org” by chance. There I saw the possibility of “faceted search” as in online shops for electronics: Each selection in a block filters the entries in the other blocks. In my opinion, the more objects there are, the better the ability to search and filter. I currently have over 3,000 audio books and filtering just by author, for example, is too rough. For example, I have the author "Andrea Camilleri". He writes books that take place in different years (in German "Handlungzeit = HZ): I see the following filter blocks:

• block of authors
• Block of Narrators
• Limitation via “Publication year”
• Limitation by length
• block the genre
• Block of TAGs
• Blocks of Class (ePup, Audio...)
• Block of Languages

additional it would be great to have "userdefined blocks". In my case: - Blocks of Type

• complete audio book
• abridged audio book
• radio play
• Live act (comedy)

- scene of action (place or country)

• USA
• Greek
• Germany
• France My items play on 114 different countries or regions: - year of action
  • 1913
  • 100 BC
  • 1984 (Georg Orwell)

- age rating

• 10 year
• 12 year
• 16 year

• - target group

• women
• men
• all

I think this can be grouped with https://github.com/advplyr/audiobookshelf/issues/1465 and https://github.com/advplyr/audiobookshelf/issues/2197

This is more filtering and not searching so I think #1465 can be used for this, what do you think?

I agree it's more filtering but i know it under the technical name "faceted search" Okay ... i found it also unter "https://www.prefixbox.com/blog/faceted-filtering/"

I was going to make this the primary thread for multiple filters since it is more detailed but realized that #1465 already has a bunch of support on it. I'll mention this thread over there and mark this as duplicate
