json.facet without a facet ...

[Bram Van Dam <br...@intix.eu>]

Howdy,

I realize that this might be a strange question, so please bear with me
here.

I've been replacing my usage of the old Stats Component (stats=true,
stats.field=foo, [stats.facet=bar]) with the new json.facet sugar. This
has been a great improvement on all fronts.

However, with the stats component I could calculate stats on a field
*without* having to facet. The new json.facet API doesn't seem to
support that in any way that I can see. Which, admittedly, makes sense,
given the name.

Faceting on a random field and setting allBuckets:true kind of
approximates the behaviour I'm after, but that's pretty ugly and
difficult (because I don't know which field to facet on and it would
have to be present in all documents etc).

Is there any way to do this that I'm not seeing?

TL;DR; Trying to calculate statistics using json.facet without faceting.

Thanks,

 - Bram

Aaaah! Thanks, that explains it. I was trying to put the statistics
under "facet":{}, instead of on the top level. Much appreciated :-)

From http://yonik.com/json-facet-api/
====================
Statistics are facets

Statistics are now fully integrated into faceting. Since we start off
with a single facet bucket with a domain defined by the main query and
filters, we can even ask for statistics for this top level bucket,
before breaking up into further buckets via faceting. Example:

json.facet={
  x : "avg(price)",           // the average of the price field will
appear under "x"
  y : "unique(manufacturer)"  // the number of unique manufacturers
will appear under "y"
}
