I have a hierarchical taxonomy of documents that I would like users to be
able to search either through search or drill-down faceting. The
documents may appear at multiple points in the hierarchy. I've got a
solution working as follows: a multivalued field labelled category which for
each
That's a good way. How does it perform?
Another way would be to store the parent topics in a field.
Whenever a parent node is drilled-into, simply search for all documents
with that parent. Perhaps not as elegant as your approach though.
I'd be interested in the performance comparison between
- plants
- animals
you have to do more requests.
Are there better ways to achieve this?
Taxonomy faceting is a bit of a mess right now, but it is also an area
where a lot is happening. For SOLR, there is

SolrJ is often used when DIH doesn't do what you wish. Using SolrJ is
really quite easy, but you're doing the DB queries yourself, often with
the appropriate jdbc driver.
Within DIH, the transformers, as Chris says, *might* work for you.

The DIH lets you code in Javascript- you can do anything.

Hi,
I watched the Lucid webcast:
http://www.lucidimagination.com/solutions/webcasts/faceting
It talks about encoding hierarchical categories to facilitate faceting. So a
category path of NonFicScience would be encoded as the multivalues
0/NonFic 1/NonFic/Science.
1) My categories are stored
