    <p>I need to write an application with which I can do complex queries using spring-data and mongodb. I have been starting by using the MongoRepository but struggled with complex queries to find examples or to actually understand the Syntax. </p> <p>I'm talking about queries like this:</p> <pre><code>@Repository public interface UserRepositoryInterface extends MongoRepository&lt;User, String&gt; { List&lt;User&gt; findByEmailOrLastName(String email, String lastName); } </code></pre> <p>or the use of JSON based queries which I tried by trial and error because I don't get the syntax right. Even after reading the mongodb documentation (non-working example due to wrong syntax).</p> <pre><code>@Repository public interface UserRepositoryInterface extends MongoRepository&lt;User, String&gt; { @Query("'$or':[{'firstName':{'$regex':?0,'$options':'i'}},{'lastName':{'$regex':?0,'$options':'i'}}]") List&lt;User&gt; findByEmailOrFirstnameOrLastnameLike(String searchText); } </code></pre> <p>After reading through all the documentation it seems that <code>mongoTemplate</code> is far better documented then <code>MongoRepository</code>. I'm referring to following documentation:</p> <p><a href="http://static.springsource.org/spring-data/data-mongodb/docs/current/reference/html/" rel="noreferrer">http://static.springsource.org/spring-data/data-mongodb/docs/current/reference/html/</a> </p> <p>Can you tell me what is more convenient and powerful to use? <code>mongoTemplate</code> or <code>MongoRepository</code>? Are both same mature or does one of them lack more features then the other?</p>

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.
