Note
This package won't be updated for Plone 5. Instead use the successor of this package: https://github.com/collective/collective.collectionfilter
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.
