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? > > Hi, > > I'm experimenting with date range faceting, and would like to use different > gaps depending on how old the date is.
