Hi there ! Is there any plan to implement hierarchical facets ? If not we may help and contribute as we need this feature for a starting project (this feature will determine if we choose elasticsearch over solr) Cheers, -- David Stendardi ---

ES has a ticket for this open on Github with lots of +1s. Solr has a few patches for this and Wiki page(s) describing how they work.

There is a plan to support it, nothing scheduled yet though (its tricky to make it performant).

What do you define as a hierarchical facet? I implemented hierarchical faceting by providing a parent field in my query when faceting. It works. But relies that your hierarchy be established at index time through fields.

I achieved that using Solr out of the box using the technique I mentioned above. In my UI, when a user "drills" down from a facet in the hierarchy, it issues another facet query on the fly. Works great.

What I like about this issue is the first comment which basically points to a new facet feature in Lucene without even understanding what it provides / how its implemented / or what its implications are :).

I think we will use your solution, because when Shay says something is a bit tricky, it is a little scaring 🙂 2011/12/30 project2501 [darreng5150@gmail.com](mailto:darreng5150@gmail.com) > I achieved that using Solr out of the box using the technique I > mentioned above. > In my UI, when a user "drills" down from a facet in the hierarchy, it > issues another facet query on the fly.

Yeah, Occum's Razor wins in this case. What the issue is trying to suggest may require real magic. My solution would work for ES too since its just vanilla lucene stuff.

To be honest, the "tricky" part would be to build one that supports different "facets" for each hierarchy, i.e. break by terms and then break by range and then ..., while still having it performing decently. A specialized one, that just does two level terms is much simpler. At the end though, we might end up with several specialized ones since with specialized ones we can make them perform better.

Have you ever had a change to talk to the LinkedIn guys or look at how Bobo ([http://sna-projects.com/bobo/](http://sna-projects.com/bobo/)) is implemented? I looked at it some time ago and it seemed to work quite well... Not sure how it plays in a distributed world like ES but LinkedIn also had/have a working integration with Sensei (somewhat similar to ES) so there may well be some good things to learn there?
