Appkit has advanced support for specifying custom URL patterns for filtering and grouping search results.
The Topic Pages module includes specialised versions of tags that work together to:
Output links with a particular path structure according to a pattern
Interpret the path of the current URL to apply filters to a search.
This allows for a rich user interface which can help a user make sense of highly 'categorised' data and map different views of the data to readable URLs.
