Commentary

Seems to be a frequently requested feature. I considered searching with a join on the ItemValues table, but figured this direct approach would likely be sufficient.

Please make sure that excludedTags are respected and that the added clause does not clash with them.

I wasn't aware of said functionality in Jellyfin! Checking...

Yes, tested and confirmed things still work as expected. My proposed change only alters the SearchScore. https://github.com/jellyfin/jellyfin/blob/master/Emby.Server.Implementations/Data/SqliteItemRepository.cs#L4523 still excludes content regardless of the score.

Haven't tested it but code seems to be fine.
Would be nice if you can squash the commits. 3 commits for a one line change seem a bit much.

I'll squash them tonight when I'm at my home PC. Thanks!

[bradbeattie]

Okay, merge squashed. Back over to you!

Considering bradbeattie/jellyfin@master...augmented-tag-searching as a second revision of this. I'll test it when I get a chance before submitting a PR.

Ok, I'm a retard. How do I implement this?

One method would be to use the unstable docker image, or wait until 10.9.
