---------------------------------------
Summary: use JSON reach DSL format for aggregations in JSON.Facet
Key: SOLR-12712
URL: https://issues.apache.org/jira/browse/SOLR-12712
Project: Solr
Issue Type: New Feature
Security Level: Public (Default Security Level. Issues are Public)
Components: Facet Module
Reporter: Mikhail Khludnev
h2. Context
[Aggregations|https://lucene.apache.org/solr/guide/7_4/json-facet-api.html#aggregation-functions
are nested into facets to handle enclosing buckets. They are supplied as a
strings expression, which is handled by ValueSourceParser or so.
h2. Problem
Passing complex expression as a comma separated list of arguments are
problematic, it leads to the verbose naming scheme or puzzling name overload
convention with optional arguments. see SOLR-12711, SOLR-12325. For example,
[StreamingExpressions|https://lucene.apache.org/solr/guide/6_6/streaming-expressions.html#StreamingExpressions-StreamingRequestsandResponses]
use name value syntax that's more powerful.
h2. Suggesition
Either introduce JSON syntax for subfacet aggregations, or if nested facets are
able to aggregate enclosing buckets, introduce a expandable parsers (plugin
point) for JSON.Facet.
