Hello Irene,
I checked all of the classes and they are all rdf:type
owl:Class (they subclass owl:Thing). I checked all of the
properties I am using as facets and the items in all of their
domains and ranges are rdf:type owl:Class. But no faceted
search (I closed and opened the model and refreshed the
caches and the swp graphs).

Jack,
I don’t believe sub-classing is either an issue or a
requirement here. Faceted search works over instances
of a class. Classes are instances of either
rdfs:Class or owl:Class. So, you need to be faceting
over either rdfs:Class or owl:Class. And properties
to select from as facets would need to be associated
with these e.g., have owl:Class in their domain.

*Subject:* Re: [topbraid-users] faceted search on
classes rather than instances?
I am trying to build faceted search across standard
models/repositories. In this case the classes are
terminals for the repository and contain all the
information an instance would carry. For example, in
the obolibrary DOID, disease obo:DOID_9352 is fully
populated with content, and the disease is unlikely
to be subclassed or instantiated.
My understanding is that these classes can
participate in faceted search under certain
circumstances. First, they have to subclassed under
one of my classes. Also, for classes to be facetable
they need to carry properties and look like resources.
I created namespaces such as the following for Symptoms:
http://siemens.com/1.0/vocab/biomed-symp
<http://siemens.com/1.0/vocab/biomed-symp>
and a prefix for it: biomed-symp. I created a class
called Symptom and then subclassed several (for the
purposes of a demo) of the classes in the obolibrary
(e.g., obo:SYMP_0000455) to biomed-symp:Symptom. I
did the same for diseases (etc.). I created facets to
bridge the repositories, such as
biomed-symp:involvesDisease, that I hung off
biomed-symp:Symptom in the defaultFacets property.
In the vocabulary, I added these properties (e.g,.
obo:SYMP_0000455 biomed-symp:involvesDisease
obo:DOID_9352).
Unfortunately this approach isn't working, so I
haven't gone far enough in one way or another, and
figure that you guys might know how to do it. Any
help would be appreciated as faceted search is very
important to this project. My faceted search in other
parts of the project, created the same way but on
class instances, are working fine.

What would you use as facets?

that is basically a taxonomy and has all of the
content at the class level, then faceted search
on the classes would provide the same benefit as
faceted search on instances.
