Yonik Seeley commented on SOLR-7214:
------------------------------------
Really high level implementation notes:
FacetRequestParser takes in JSON and creates FacetRequest objects.
FacetRequest objects create FacetProcessor objects on specific shards that are
responsible for doing the faceting.
FacetRequest objects can also create a FacetMerger, which is responsible for
merging responses from multiple shards.
To the degree possible, we push smarts down to the leaves rather than making
them dumb.
For example, instead of modifying things like "offset" or "limit" at the top
level, the shards are aware that they are in a distributed search and know how
to do that themselves. This is much less error prone as we can avoid modifying
the original facet request.
Things are designed to be fully pluggable as well. For example, someone can
design their own aggregation and it has the right methods to handle both low
level implementation as well as high level distributed search merging.

> Project: Solr
> Issue Type: New Feature
> Reporter: Yonik Seeley
> Attachments: SOLR-7214.patch

>
> Overview is here: http://heliosearch.org/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
