> Key: SOLR-14518
> URL: https://issues.apache.org/jira/browse/SOLR-14518
> Project: Solr
> Issue Type: New Feature
> Security Level: Public(Default Security Level. Issues are Public)
> Reporter: Joel Bernstein
> Priority: Major
>
> There are scenarios where documents are partitioned across shards based on
> the same field that the *unique* agg is applied to with JSON facets. In this
> scenario exact counts can be calculated by simply sending the bucket level
> unique counts to the aggregator where they can be merged. Suggested syntax is
> to add a boolean flag to the unique function: *unique*(field, true).
> The true turns on the "partitioned" unique logic. The default is false.
