Body
When you query with this form: <pre class="lang-cs prettyprint-override"><code>session.Query<Entity>("IndexName") </code></pre> You are asking for all items of that index to be returned from the query, and then telling the RavenDB client to deserialize them all as the type you specified. Normally, that works out quite well because a specific index would be built for the types you're working with. For example, you would usually build your own index of subscriptions for a specific purpose, and query that: <pre class="lang-cs prettyprint-override"><code>session.Query<Subscription>("Subscriptions/ByWhatever") </code></pre> or if you built the index from C#, you might like this syntax instead to avoid the string: <pre class="lang-cs prettyprint-override"><code>session.Query<Subscription, Subscriptions_ByWhatever>() </code></pre> You could also just let Raven build an index for you automatically: <pre class="lang-cs prettyprint-override"><code>session.Query<Subscription>() </code></pre> Since you used the built-in <code>Raven/DocumentsByEntityName</code> index, you are returning all documents in the database, not just those that are subscriptions. Since only some can be deserialized as a <code>Subscription</code> type, the others are failing with serialization errors. If you'd like to continue to use that index, you would need to filter it to just those of that type: <pre class="lang-cs prettyprint-override"><code>session.Advanced.LuceneQuery<Subscription>("Raven/DocumentsByEntityName") .WhereEquals("Tag", "Subscriptions") </code></pre> The <code>LuceneQuery</code> form is easier here, since you are filtering a field by its string name. You could use a regular LINQ query, but you'd have to create a type that contains the <code>Tag</code> field, like this: <pre class="lang-cs prettyprint-override"><code>class RDBENIndexEntry { public string Tag { get; set; } } ... session.Query<RDBENIndexEntry>("Raven/DocumentsByEntityName") .Where(x => x.Tag == "Subscriptions").OfType<Subscription>() </code></pre>

1. COThanks Matt, unfortunately that doesn't resolve the problem. As suggested I pulled back the results with the advanced query. That bit works, but the serilaization post retrieval fails. I'll edit the original with details.

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.
