Shawn Heisey commented on SOLR-5302:
------------------------------------
I love new functionality. Thank you for all the time and effort!
I was going to suggest that you just replace the existing StatsComponent rather
than create a new component, but as I look a little bit into things, it looks
like it might not be a new component from the user/admin perspective, just the
code perspective. I haven't looked in-depth, but I do see a new class in the
patch, so I'm slightly confused. That confusion may clear up after I've looked
deeper.
Side note, and most likely not your fault at all: Your PDF text is invisible in
my in-browser PDF viewer. Windows 8 Pro, Firefox 24.0. Everything is fine if
downloaded and opened in Adobe Reader. I think this is probably using the PDF
viewer built into Windows 8, which *sucks*.

> * 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)
