Michel Lemay commented on SOLR-5302:
------------------------------------
1) In my opinion, it should be implemented to be parallel with SimpleFacet
feature list. Also, it's mentioned in the documentation of this feature
request: "The AnalyticsComponent supports the following features:
All functionality of StatsComponent (...Sorting (bucket name or any stat in the
bucket..."
2) I derived from an example found at the botton of this document:
https://issues.apache.org/jira/secure/attachment/12606794/Statistical%20Expressions.pdf
Note, double() also have the same behavior.

> This ticket is to track a "replacement" for the StatsComponent. The
> AnalyticsComponent supports the following features:
> * All functionality of StatsComponent (SOLR-4499)
> * Field Faceting (SOLR-3435)
> ** Support for limit
> ** Sorting (bucket name or any stat in the bucket
> ** Support for offset
> * Range Faceting
> ** Supports all options of standard range faceting
> * Query Faceting (SOLR-2925)
> * Ability to use overall/field facet statistics as input to range/query
> faceting (ie calc min/max date and then facet over that range
> * Support for more complex aggregate/mapping operations (SOLR-1622)
> ** Aggregations: min, max, sum, sum-of-square, count, missing, stddev, mean,
> median, percentiles
> ** Operations: negation, abs, add, multiply, divide, power, log, date math,
> string reversal, string concat
> ** Easily pluggable framework to add additional operations
> * New / cleaner output format
> Outstanding Issues:
> * Multi-value field support for stats (supported for faceting)
> * Multi-shard support (may not be possible for some operations, eg median)
