There were a few questions on the similar topic but their resolutions do not seem to fit my case. Env: Solr4.2.1, Tomcat 7 I am trying to index public movielens data, and started (as everybody) with the 'example' core. I have removed some fields from the schema not relevant to me, and added others to index movielens fields: <pre><code><field name="id" type="string" indexed="true" required="true" stored="true" multiValued="false" />  <field name="user_number" type="string" indexed="true" stored="true" multiValued="false" /> <field name="item_number" type="text_general" indexed="true" stored="true"/> <field name="rating" type="int" indexed="true" stored="true" /> <field name="timestamp" type="date" indexed="true" stored="true"/>   <field name="age" type="int" indexed="true" stored="true" /> <field name="gender" type="text_general" indexed="true" stored="true"/> <field name="occupation" type="text_general" indexed="true" stored="true"/> <field name="zipcode" type="text_general" indexed="true" stored="true"/>  ... <uniqueKey>id</uniqueKey> </code></pre> I am adding all fields in my Java indexer, including a generated 'id' field, I am also printing out each field I am adding , so from the console output below you can see that I indeed add the 'id' field, along with others... Yet, I am getting the following error: <pre><code>May 5, 2013 9:43:06 AM org.apache.solr.client.solrj.impl.HttpClientUtil createClient INFO: Creating new http client, config:maxConnections=128&maxConnectionsPerHost=32&followRedirects=false indexUserData() started for file: u.user indexUserData() processing line: 1|24|M|technician|85711 adding field: [user_number, 1] adding field: [id, u_user_1] adding field: [age, 24] adding field: [gender, M] adding field: [occupation, technician] adding field: [zipcode, 85711] Exception in thread "main" org.apache.solr.common.SolrException: Document is missing mandatory uniqueKey field: id at org.apache.solr.client.solrj.impl.HttpSolrServer.request(HttpSolrServer.java:404) </code></pre> Any idea what I am missing? Thank you! Marina

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.
