May I ask how you implemented getting the facet counts for each

you use a facet-query per interval?
And perhaps for inspiration a link to the site you implemented this ..

I love the idea of a sparkline at range-sliders. I think if I have
time, I
might add them to the range sliders on our site. I already have all
the data
since I show the count for a range while the user is dragging by
storing the
facet counts for each interval in javascript.
Hi,
Sorry, seems I pressed send halfway through my mail and forgot about
it. The site I implemented my numerical range faceting on is
http://www.mysecondhome.co.uk/search.html and I got the facets by
making a small patch for Solr
(https://issues.apache.org/jira/browse/SOLR-1240) which does the same
thing for numbers what date faceting does for dates.
The biggest issue with range-faceting is the double counting of edges
(which also happens in date faceting, see
https://issues.apache.org/jira/browse/SOLR-397). My patch deals with
that by adding an extra parameter which allows you specify which end
of the range query should be exclusive.
A secondary issue is that you can't do filter queries with one end
inclusive and one end exclusive (i.e. price:[500 TO 1000}). You can
get around this by doing "price:({500 TO 1000} OR 500)". I've looked
into the JavaCC code of Lucene to see if I could fix it so you could
mix [] and {} but unfortunately I'm not familiar enough with it to
get it to work.

Hi,
I was supposed to work on something else but I just couldn't resist,
and just implemented some bar-graphs for the range sliders and I
really like it. In my case it was really easy, all the data was
already right there in javascript so it's not causing additional
server side load. It's also really nice to see the graph updating when
a facet is selected/changed.
