Gus Heck created SOLR-10132:
-------------------------------
Summary: Support facet.matches to cull facets returned with a regex
Key: SOLR-10132
URL: https://issues.apache.org/jira/browse/SOLR-10132
Project: Solr
Issue Type: New Feature
Security Level: Public (Default Security Level. Issues are Public)
Components: faceting
Affects Versions: 6.4.1
Reporter: Gus Heck
I recently ran into a case where I really wanted to only return the next level
of a hierarchical facet, and while I was able to do that with a coordinated set
of dynamic fields, it occurred to me that this would have been much much easier
if I could have simply used PathHierarchyTokenizer and written
&facet.matches="/my/current/prefix/[^/]+$"
thereby limiting the returned facets to the next level down and not return the
additional N levels I didn't (yet) want to display (numbering in the thousands
near the top of the tree). I suspect there are other good use cases, and the
patch seemed relatively tractable.
