I guess, to generalize the idea, is to have some support for aggregation
functions. average anyone ;-) ? It would also be very useful to be able
to define the field that is being aggregated. For example, in a flight
reservation web site we developed we needed to show facets on different
flight fields (e.g. connections count, departure/arrival times, etc..)
but next to each facet value we needed to show the cheapest flight price.

function foo has not been implemented. Can I write my own foo function and
plug it in somewhere? I'm theorizing though... I'll look at the patch later.

What do you mean? Right now you send an extra parameter
f.weight.facet.statistical=true and it will add statistical information to
the facet field response.
What I don't like is that I made the the changes to the SimpleFacet class
itself, it would nicer to have the ability to specify a different strategy
(different class) instead. So the code won't grow too much and we don't have
lots of ifs.

I know that I would definately be interested in that. :)

Quoting Jonathan Ariel :
Ok. So I have a version of solr with a small modification to the
SimpleFacet
class where you can send a parameter to tell that you want some more
info.
It'll bring back a list with the max and min values as well as the SD,
CV
and Mean for the facet values.
If you are interested I could generate a patch and add it to JIRA.
What do you think?

Hi!I'm looking for a way to get the maximum and minimum value of a
field
(like price) in a specific query. First I thought about using facet
for
that, but since price may have lots of different and unique values, a
facet
is not a good idea.
Any thoughts about how can I achieve this?
Thanks!
