What I did was: 

-added some :0 use in zebradb/retrieval-info-bib-dom.xml like:

<retrieval syntax="xml" name="zebra::facet::subject:0:100"/>

- Edited marc_defs/marc21/biblios/biblio-koha-indexdefs.xml and added an
occurence of

<target_index>Subject:0</target_index>
after every
<target_index>Subject:p</target_index>

this could be narrowed down later (we might not need facets for all thsoe
fields), but I wanted to make sure :0 contained the same as :p for subject, for
testing purposes.

- Run 
xsltproc ~/koha-dev/etc/zebradb/xsl/koha-indexdefs-to-zebra.xsl
biblio-koha-indexdefs.xml > biblio-zebra-indexdefs.xsl

to regenerate the xsl file,

- Then reindex :-(

And then search using:
 Z> format xml
 Z> elem zebra::facet::subject:0:100

I also had zebra::facet::subject:p defined to compare the results over the same
search.
