Hi Ufuk, Thanks for the tips !
It works fine with this : http://localhost:8983/solr/db001/select? facet.contains.ignoreCase=true &fl=ap,in &indent=true &q.op=OR &q=ti%3Atreat* &rows=1 &facet=true &facet.range.gap=%2B1YEAR (the GAP) &facet.range=pd (field to count) &facet.range.start=1800-01-01T23:59:59Z (date start) &facet.range.end=2024-07-01T23:59:59Z (date end, I don't know yet how can I tell "take all") &facet.mincount=1 (To delete frequency = 0) Thanks a lot ! PS: I continue to search how to indicate "take all" Cordialement, Best Regards Bruno Mannina www.matheo-software.com www.patent-pulse.com Mob. +33 0 634 421 817 -----Message d'origine----- De : ufuk yılmaz [mailto:uyil...@vivaldi.net.INVALID] Envoyé : lundi 1 juillet 2024 15:38 À : users@solr.apache.org Objet : Re: Get only year from a date field for a copy field ? Hi Bruno, Did you consider using a range facet with gap being 1 year? If that works for you, you can avoid reindexing altogether. https://solr.apache.org/guide/8_1/json-facet-api.html Try specifying gap as "1YEARS" or "+1YEARS" (I forgot if plus sign was required or not) Sincerely Ufuk Yilmaz — > On Jul 1, 2024, at 17:51, Bruno Mannina <bmann...@matheo-software.com> wrote: > > Hi Solr Team, > > > > Is it possible to create a copy field where the source is a date-time > field to extract only the year ? > > > > I have 2024-07-01T253:59:59Z for the date field and store/index a copy > field with only 2024. > > > > The goal is to have faceting only on Year information. > > > > Note: I haven't the possibility to re-create my source files to index > due to the huge volume (more than 15To of data). > > Note2: my index is not yet build. > > > > Cordialement, Best Regards > > Bruno Mannina > > <http://www.matheo-software.com/> www.matheo-software.com > > <http://www.patent-pulse.com/> www.patent-pulse.com > > Mob. +33 0 634 421 817 > > > > > > -- > Cet e-mail a été vérifié par le logiciel antivirus d'Avast. > www.avast.com -- Cet e-mail a été vérifié par le logiciel antivirus d'Avast. www.avast.com
