Body
I am configuring Solr for the very first time. Google has yielded very little insight. I see questions postesd that are similar to my issue, but not the same. I have a SolrCore called collection1 in ~/solr-home/solr. I have verified that its configuration is read by Solr when it starts up. Here is the declaration for my core in ~solr-home/solr/solr.xml: <pre><code> <cores adminPath="/admin/cores" defaultCoreName="collection1" host="${host:}" hostPort="${jetty.port:}" hostContext="${hostContext:}" zkClientTimeout="${zkClientTimeout:15000}"> <core name="collection1" instanceDir="collection1" /> </code></pre> Solr is running on Ubuntu. I am attempting to inmport from Microsoft SQL Server running on Windows, but I don't get as far as making the JDBC connection. Here is my data import declaration: <pre><code> <requestHandler name="/dataimport" class="org.apache.solr.handler.dataimport.DataImporHandler"> <lst name="defaults"> <str name="config">data-config.xml</str> </lst> </code></pre> My core seems like it is starting up at first. From the log file: <pre><code>INFO: Creating SolrCore 'collection1' using instanceDir: solr/collection1 May 09, 2013 2:52:22 PM org.apache.solr.core.SolrResourceLoader <init> INFO: new SolrResourceLoader for directory: 'solr/collection1/' May 09, 2013 2:52:22 PM org.apache.solr.core.SolrResourceLoader replaceClassLoader INFO: Adding 'file:/home/moon/solr-home/solr/collection1/lib/solr-dataimporthandler-4.2.0.jar' to classloader May 09, 2013 2:52:22 PM org.apache.solr.core.SolrResourceLoader replaceClassLoader INFO: Adding 'file:/home/moon/solr-home/solr/collection1/lib/solr-dataimporthandler-extras-4.2.0.jar' to classloader </code></pre> ... <pre><code>INFO: [collection1] Opening new SolrCore at solr/collection1/, dataDir=/solr-home/data/ May 09, 2013 2:52:25 PM org.apache.solr.core.JmxMonitoredMap <init> INFO: JMX monitoring is enabled.

Guidance

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.
