I've been experimenting with that, but that fq wouldn't limit my facet
counts adequately. Since the document has both an accessionWF and a
digitizationWF, the fq would match (and count) the document no matter what
the status for each process.
I suppose I could do something like this:
<field name="status_wps">accessionWF:start-accession:completed</field>
<field name="status_wps">accessionWF:cleanup:waiting</field>
<field
name="status_wps">accessionWF:descriptive-metadata:completed</field>
<field name="status_wps">accessionWF:content-metadata:completed</field>
<field name="status_wps">accessionWF:rights-metadata:completed</field>
<field name="status_wps">accessionWF:publish:completed</field>
<field name="status_wps">accessionWF:shelve:error</field>
<field name="status_wsp">accessionWF:completed:start-accession</field>
<field name="status_wsp">accessionWF:waiting:cleanup</field>
<field
name="status_wsp">accessionWF:completed:descriptive-metadata</field>
<field name="status_wsp">accessionWF:completed:content-metadata</field>
<field name="status_wsp">accessionWF:completed:rights-metadata</field>
<field name="status_wsp">accessionWF:completed:publish</field>
<field name="status_wsp">accessionWF:error:shelve</field>
<field name="status_swp">completed:accessionWF:start-accession</field>
<field name="status_swp">waiting:accessionWF:cleanup</field>
<field
name="status_swp">completed:accessionWF:descriptive-metadata</field>
<field name="status_swp">completed:accessionWF:content-metadata</field>
<field name="status_swp">completed:accessionWF:rights-metadata</field>
<field name="status_swp">completed:accessionWF:publish</field>
<field name="status_swp">error:accessionWF:shelve</field>
and use a PathHierarchyTokenizerFactory with : as the delimiter. Then I
could use facet.field=status_wps&f.status_wps.facet.prefix=accessionWF: to
get the counts for all the accessionWF processes and statuses, then repeat
using status_wsp and status_swp for the various inversions. I was hoping for
something easier. :)
