This is resulting in a different number of tokens in different documents, which is causing the error. Use a field that is non-tokenized, e.g., change the type of the "title" field to "string". If you need a tokenized "title" field, copy the field to another of type "string", and sort on that field instead. Please see http://wiki.apache.org/solr/CommonQueryParameters#sort Regards, Gora
