Description

Our application processes queries like so:

        try {
            final SolrServer server = getServer();
            final QueryResponse resp = server.query(query);
            return resp;
        } catch (final SolrServerException e) {
             /// bad things probably happened, invoke error processing and possibly switch to the backup
        }

Given SOLR-874 with dismax queries sometimes causing ParseException from Lucene, I'd like to be able to interrogate the cause chain of the SolrServerException. For example if I found ParseException in the chain, I could provide a specific error message and know that it's not necessary to switch to the backup server.

As it is now, getCause is giving null. The undesirable fix right now is looking inside the toString/description for the "ParseException" phrase.

Thanks.
