add an "or" option

[Turhvjbufv]

Describe your suggested feature

In tachisy there an option to search for tags, problem is that you cannot search for romance or comedy, you can only search for one at a time or both tags, same problem in filter, I can only do bookmarks and downloads or bookmarks or downloads
An or option would be very nice

Other details

Sorry if I missed an issue like that if there was already, as it's not very helpful to search "or" on GitHub I might have missed an issue like that. sorry in advance

Just realized something, in filter it doesn't really matter as you can disable the other filters and not touch the filters which you wish to do "or" on and it would have the same effect, not so easy in searching tags as there are multiple tags and not just 3
