Erick Erickson updated SOLR-5302:
---------------------------------
Attachment: SOLR-5302.patch
Some of the tests were failing because, at least on my Mac, the paths to the
various files in test-files weren't correct when I ran "ant test" from the
shell. Current implementation succeeds both from the shell and IntelliJ.
We'll see if this breaks on Jenkins.
Meanwhile, committing on trunk. Anyone who wants to give it a whirl, feedback
greatly appreciated!
Awesome stuff Steven! Here I thought I had a big patch at 150K or so :)
This has considerable documentation, anyone want to volunteer to incorporate it
into the Wiki?

> 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)
