regexp will match the whole term. So, if you have stemming on, magnetic may well stem to magnet, and that is the term against which the regexp is executed.
If you want to do the regexp against the whole field, then you need to do it against a string version of that field. The process of using a regexp (and a wildcard for that matter) is: * search through the list of terms in your field for terms that match your regexp (uses an FST for speed) * search for documents that contain those resulting terms Upayavira On Wed, Oct 21, 2015, at 12:08 PM, Bruno Mannina wrote: > title:/magnet.?/ doesn't work for me because solr answers: > > |title = "Magnetic folding system"| > > but thanks to give me the idea to use regexp !!! > > Le 21/10/2015 18:46, Upayavira a écrit : > > No, you cannot tell Solr to handle wildcards differently.
