Dariusz, This problem is most probably occurring because solr does not store dates in the format you've specified. It's something like: 2017-10-08T12:23:00Z. You'll probably need to specify your date in your efi feature in the manner above to get it to work.
You can find more details on dates here: https://lucene.apache.org/solr/guide/6_6/working-with-dates.html On Wed 18 Oct, 2017, 19:16 Dariusz Wojtas, <dwoj...@gmail.com> wrote: > Hi, > I am using the LTR functionality (SOLR 7) and need to define a feature that > will check if the given request parameter of type date (ie.
