    <p>I am having a weird issue with Solr. I am using Rails 3 with Sunspot gem and everything was fine when I was running off my local instance of Solr. But once I tried running same code in a different environment with more data (10M records or so as opposed to 20K in local environment) and remote Solr instance, Solr started throwing errors like this when I run rake sunspor:reindex:</p> <pre><code>Solr Response: Internal Server Error </code></pre> <p>And tomcat6 logs would contain an error like this: </p> <pre><code>Jul 5, 2011 10:14:29 AM org.apache.solr.core.SolrCore execute INFO: [] webapp=/solr4 path=/update params={wt=ruby} status=0 QTime=6 Jul 5, 2011 10:14:30 AM org.apache.solr.update.processor.LogUpdateProcessor finish INFO: {add=[Project 395767, Project 396057, Project 396078, Project 396139, Project 396368, Project 396409, Project 396421, Project 396442, ... (8 added)]} 0 73 Jul 5, 2011 10:14:30 AM org.apache.solr.common.SolrException log SEVERE: java.io.FileNotFoundException: /opt/solr/solr4/data/index/_0.fnm (No such file or directory) </code></pre> <p>It seems happening at random times (not the same project causes it).</p> <p>I tried deleting Solr index folder and rebuilding index from scratch. That didn't have any effect except that Solr started complaining about different .fnm file. </p> <p>Same error happens if I'm building my models in Rails. I was populating the database from .csv file and Sunspot would choke at random records </p> <pre><code>Solr Response: Internal Server Error </code></pre> <p>with the same missing .fnm file error on Solr server.</p> <p>Did anyone experience anything like that? Any ideas at all would be welcome!</p>

    1. COI think I have figured it out on my own. Problem was caused by incorrect Solr configuration. There were two Solr instances pointing to the same index directory.

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.
