Is there a way to make a join query?

[exports]

For example, I have a many-to-many relationship, and I want to get users that have specific tag id, I tried with ?filter[tags][id]=id but it's not working.

class User {
  @ManyToMany
  private Set<Tag> tags;
}

class Tag {
  @ManyToMany
  private Set<User> users;
}

Need some more information.

Are you using katharsis-jpa or vanilla katharsis?

If you are not using katharsis-jpa, then you have to provide the filtering yourself in the implementation of your Repository or RelationshipRepository.

If you are using katharsis-jpa, then @remmeier can add something about how that is supposed to work.

I'm using katharsis-jpa :)
