Shawn Heisey commented on SOLR-5302:
------------------------------------
bq. This is link I meant in the pdf:
https://cms.prod.bloomberg.com/team/display/fdns/Search+Analytics+Component
If I had to guess, I would say that is an internal website for Bloomberg,
something that only employees can get to. If they intend it for public
consumption, they'll need to publish the data on a public website and fix the
links in the PDF.
bq. Any idea when the future 5x could be released?
Quick answer: 5.0 is many months away. It's impossible to give any kind of
release date prediction. Hopefully this particular feature will end up in a
4.x release, once Erick (or another committer) has the time to devote to giving
the code a thorough review.
Longer answer:
At this time, nobody has come up with a timeframe for Solr 5.0. Once somebody
decides we're going to begin the process and agrees to be the release manager,
a LOT has to happen, and there's really no way to make it happen quickly.
Even if we began the 5.0 release process tomorrow and everything were to be
extremely smooth, I don't think you'd even see a 5.0-ALPHA release for a few
months. We can't begin the release process that soon, so it's going to be even
longer. One of the big items still left to do is to embed the HTTP server
layer and make Solr into a standalone application.
I wasn't involved with the development when 4.0 was released, so I don't know
how much time passed between the beginning of the 4.0 release process and
4.0-ALPHA, but I can tell you that there were three months between 4.0-ALPHA
and 4.0-FINAL.

> 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)
