Hi Ahmet,
I forgot to include what I did for one customer :
1) Using StatsComponent I get min and max values of the field (year)
2) Calculate "smart gap/range values" according to minimum and maximum.
3) Re-issue the same query (for thee second time) that includes a set of
facet.query.
It's amazing, everyone I am talking with about this problem seems to
remember some hack(s) to work around the problem ;-)
On one hand it shows, there are some options (and thanks for giving me
some more!) but on the other hand it also shows how much need there is
for a real solution like SOLR-1672. I really hope Shawn finds some time
to make it work.
