Filtering

A filter is a combination of predicates that have to be satisfied. hircine provides a filter interface that allows using almost any type of metadata as a predicate and can therefore build complex and expressive queries.

Filtering comics

If given multiple types of predicates, all of them have to match. If one type of predicate contains multiple selections, the selected mode determines how they are combined:

Mode

Behaviour

∀ (“for all”)

matches if all given entities match

∃ (“there exists”)

matches if any of the given entities match

= (“exactly”)

matches if entities are present exactly as given

For example, in the picture above, a comic only matches if all of the following is true:

  • It is tagged as female:idol or :tights.

  • It is tagged with the artist 40hara.

  • It is rated as Questionable.

  • It is uncensored.

  • It is in any language except Japanese.

Matching empty sets

Each type of predicate may also match on the ∅ empty set. If enabled, the predicate only matches if the object does not contain any entities of that type.

Important

If matching on the empty set, make sure there are no selections present in the corresponding dropdown menu, as otherwise the filter will never match.
