(I don't know where filter queries came in.)
If you get a result with
- <lst name="facet_counts">
<lst name="facet_queries" />
- <lst name="facet_fields">
- <lst name="features">
<int name="0">40</int>
<int name="000">60</int>
<int name="1">20</int>
<int>2</int>
</lst>
</lst>
</lst>
and you want to get facets of '000' and Null, this query will include
documents that match those facets:
&q=features:000 OR -features[* TO *]
