Peter Davis created SOLR-7119:
---------------------------------
Summary: Tag and exclude local params don't work for interval
facet as documented
Key: SOLR-7119
URL: https://issues.apache.org/jira/browse/SOLR-7119
Project: Solr
Issue Type: Bug
Components: faceting
Affects Versions: 4.10.3
Reporter: Peter Davis
The documentation for [Faceting - Tagging and Excluding
Filters|https://cwiki.apache.org/confluence/display/solr/Faceting#Faceting-TaggingandExcludingFilters]
says _(emphasis mine)_:
bq. Filter exclusion is supported for *all* types of facets.
But using the {{\{!ex}}} local param with an *interval* facet does not work.
This query returns 0 in `facet_counts.facet_intervals.weight`.
{code}
http://.../select?q=*:*&fq={!tag=weight}weight:[45 TO
100}&facet=true&facet.interval=weight&facet.interval.set={!ex=weight}[*,45)
{code}
A workaround appears to be to use query facets instead of interval facets.
This query returns the expected facet count:
{code}
http://.../select?q=*:*&fq={!tag=weight}weight:[45 TO
100}&facet=true&facet.query={!ex=weight}weight:[* TO 45}
{code}
I want to use this for a _multi-select_ faceting UI. Some of our facets are
field or query facets while others are intervals.
At least, it would be helpful if the documentation said which kinds of facets
this works for.
Looking at the code in {{IntervalFacets.java}}, it appears that {{\{!key}}} is
the only local param currently supported.
