Faceted navigation filter for collection results.

This portlet allows you to filter collections results for additional catalog metadata. For example, you can add a subject filter, but also a filter for authors or portal types. The "Collection Filter" portlet can be used to build tag clouds.

The filter types can be extended (see: collective.portlet.collectionfilter.vocabularies).

Besides the "Collection Filter" portlet there is also a "Collection Search" portlet for doing a fulltext search on the collection results.

This package is a fork of collective.portlet.collectionbysubject by Rok Garbas.
