Hi Ralf, Dismax querparser does not allow fielded queries. e.g. field:something
Consider using edismax query parser instead. Also debugQuery=on will display informative output how query parsed analyzed etc. ahmet --- On Tue, 2/12/13, Ralf Heyde <ralf.he...@gmx.de> wrote: > From: Ralf Heyde <ralf.he...@gmx.de> > Subject: DisMax Query & Field-Filters (ASCIIFolding) > To: solr-user@lucene.apache.org > Date: Tuesday, February 12, 2013, 5:25 PM > Hello, > > I have an interesting behaviour. > > I have a FieldType "Text_PL".
