Harris, This depends entirely on how you set up your analyzers in Solr. Nutch will send the parsed text verbatim to Solr. It's likely you have some filter stripping your non-alphanum chars such as a misconfigured word delimiter filter.
Consult the Solr docs and mailing list. Cheers, > Are you sure this is the case?
