    2. COThank you for the reply. I have already saw this post but my problem is how to set this classpath. Do I need to change something in the solrconfig.xml or in my Java Program including this class ? I have found this class here : solr-4.3.0\lucene\analysis\common\src\java\org\apache\lucene\analysis\util\ResourceLoader. What do I need to do with this file ?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
