So, what do you have already? Did you get as far as having a Solr document that has a full name as one of the fields and you just want to extract the date portion into a separate field?
If so, your best bet is probably a custom UpdateRequestProcessor chain that will 1) Copy filename field to date field 2) Transform it with a regular expression to just leave the date part 3) Map it to date using custom format (see schemaless configs for one of those) Regards, Alex. ---- Solr Analyzers, Tokenizers, Filters, URPs and even a newsletter: http://www.solr-start.com/ On 2 March 2015 at 12:44, Mirko Torrisi <mirko.torr...@ucdconnect.ie> wrote: > I forgot to add that the txt files are divided in directory following this > rule: /YYYY/MM/**files**. > > Regards, > Mirko
