OK, that explains it. I thought that it would match the params, so that it
would match the first parameter facet.range=scheduledate_start_tdate with the
first parameter
f.scheduledate_start_tdate.facet.range.start=1990-01-01T11:00:00.000Z, the
second parameter facet.range=scheduledate_start_tdate with the second
parameter
f.scheduledate_start_tdate.facet.range.start=2011-01-01T11:00:00.000Z and so
on.
what you want to do can be accomplished (as of Solr 4.3 - see SOLR-1351) by
using local params in the facet.range (or facet.date) params...
http://localhost:8983/solr/select?q=*:*rows=0facet=truefacet.range={!
facet.range.start=NOW/MONTH%20facet.range.end=NOW/MONTH%2B1M
ONTH%20facet.range.gap=%2B1DAY}manufacturedate_dtfacet.range={!fa
cet.range.start=NOW/MONTH%20facet.range.end=NOW/MONTH%2B1MO
NTH%20facet.range.gap=%2B5DAY}manufacturedate_dt
Thanks for this info. I'm not sure it is easy to upgrade Solr for us though,
since it is more or less integrated into the CMS we use.
But I actually realized that for this particular case, we don't need different
gap sizes. We can use the before and after metadata instead.

What you are trying to do is possible, but the SolrJ helper methods you
are using predates the ability and doesn't currently work the way it
should...
: solrQuery.addDateRangeFacet(scheduledate_start_tdate, date1, date2,
+1YEAR);
: solrQuery.addDateRangeFacet(scheduledate_start_tdate, date3, date4,
+1MONTH);
the addDateRangeFacet method you are calling is just syntactic sugar for
the add(String,String) method called on the various params: facet.range,
facet.range.start, etc
You can see that in the resulting URL you got the params are duplicated --
the problem is that when expressed this way, Solr doesn't know when the
different values of the start/end/gap params should be applied -- it just
loops over each of the facet.range fields (in your case: the same field

I've opened a new issue to track fixing these sugar methods -- patches
to improve this would certainly be welcome, but note that it regardless of
hte SolrJ behavior you'll need to upgrade to at least Solr 4.3 for the
server side piece to work, and you cna work arround hte client side
behavior by calling add(String,String) directly.

Date range faceting with various gap sizes?
Hi, I'm experimenting with date range faceting, and would like to use different gaps depending on how old the date is. But I am not sure on how to do that. This is what I have tried, using the java API Solrj 4.0.0 and Solr 4.1.0: solrQuery.addDateRangeFacet(scheduledate_start_tdate, date1, date2, +1YEAR); solrQuery.addDateRangeFacet(scheduledate_start_tdate, date3, date4, +1MONTH); solrQuery.setFacetMinCount(1); The first date interval is between 1990 and 2011, and the second interval is 2011 to 2014. This results in this URL: http://localhost:8080/solr/select?q=*:*facet.range=scheduledate_start_tdatefacet.range=scheduledate_start_tdatef.scheduledate_start_tdate.facet.range.start=1990-01-01T11%3A00%3A00.000Zf.scheduledate_start_tdate.facet.range.start=2011-01-01T11%3A00%3A00.000Zf.scheduledate_start_tdate.facet.range.end=2011-01-01T10%3A59%3A59.999Zf.scheduledate_start_tdate.facet.range.end=2014-01-01T11%3A00%3A00.000Zf.scheduledate_start_tdate.facet.range.gap=%2B1YEARf.scheduledate_start_tdate.facet.range.gap=%2B1MONTHfacet=truefacet.mincount=1wt=xmlindent=true And the response contains this: lst name=facet_ranges lst name=scheduledate_start_tdate lst name=counts int name=2006-01-01T11:00:00Z207/int int name=2007-01-01T11:00:00Z818/int int name=2008-01-01T11:00:00Z811/int int name=2009-01-01T11:00:00Z618/int int name=2010-01-01T11:00:00Z612/int /lst str name=gap+1YEAR/str date name=start1990-01-01T11:00:00Z/date date name=end2011-01-01T11:00:00Z/date /lst lst name=scheduledate_start_tdate lst name=counts int name=2006-01-01T11:00:00Z207/int int name=2007-01-01T11:00:00Z818/int int name=2008-01-01T11:00:00Z811/int int name=2009-01-01T11:00:00Z618/int int name=2010-01-01T11:00:00Z612/int /lst str name=gap+1YEAR/str date name=start1990-01-01T11:00:00Z/date date name=end2011-01-01T11:00:00Z/date /lst /lst Right away I notice that this is incorrect. The second facet range incorrectly uses the same gap, start and end-values as the first one. Can someone understand why? And is there a way to make this work? Regards /Jimi
SV: Date range faceting with various gap sizes?
Directly after I sent my email, I tested using two different field names, instead of the same field name for both range facets. And then it worked. So, it seems there is a bug that can't handle multiple range facets for the same field name. A workaround is to use a copyfield to another field, and do the second range facet for that second field name. But surely this is a bug in Solr, right? Maybe it has already been reported, but I couldn't find anything. /Jimi -Ursprungligt meddelande- Från: jimi.hulleg...@svensktnaringsliv.se [mailto:jimi.hulleg...@svensktnaringsliv.se] Skickat: den 12 november 2013 15:08 Till: solr-user@lucene.apache.org Ämne: Date range faceting with various gap sizes?
