Crawdaddy commented on SOLR-7214:
---------------------------------
Ran into a bug in the Facet Module around shards tolerant behavior. If a shard
is down, a 500 error is thrown with an NPE. If we specify shards.tolerant=true
in our Solr config, I would expect partial responses in the faceting module as
well I think, right?

> --------------
>
> Key: SOLR-7214
> URL: https://issues.apache.org/jira/browse/SOLR-7214
> Project: Solr
> Issue Type: New Feature
> Reporter: Yonik Seeley
> Assignee: Yonik Seeley
> Fix For: 5.1
>
> Attachments: SOLR-7214.patch
>
>
> Overview is here: http://yonik.com/json-facet-api/
> The structured nature of nested sub-facets are more naturally expressed in a
> nested structure like JSON rather than the flat structure that normal query
> parameters provide.
> Goals:
> - First class JSON support
> - Easier programmatic construction of complex nested facet commands
> - Support a much more canonical response format that is easier for clients to
> parse
> - First class analytics support
> - Support a cleaner way to do distributed faceting
> - Support better integration with other search features
