I'm trying to filter results to a few channels and I want to exclude entries in the news channel with the category of "Internal News". The following returns no results.
{exp:super_search:results
channel="not blog|breakouts|calendar|work|heros" sort_by="asc"
limit="15"
status="open"
category="-Internal News"
relevance="title=500+summary=10+body=2"
relevance_proximity="yes"
highlight_keywords="strong"
smart_excerpt="yes"}
...
{/exp:super_search:results}
I've tried category="-internal-news" and I've tried the category filter in the search form with no luck.
sort_by=""
is not a valid parameter.
