    <p>First, you'll need to make sure that you store the fields you are indexing. This is required so you can get the <em>index results</em> back, instead of the <em>documents</em> that matched the index.</p> <p>Add this to the bottom of your index definition:</p> <pre><code>StoreAllFields(FieldStorage.Yes); </code></pre> <p>Or if you want to be more verbose, (perhaps your index is doing other things also):</p> <pre><code>Store(x =&gt; x.Game, FieldStorage.Yes); Store(x =&gt; x.Member, FieldStorage.Yes); Store(x =&gt; x.List, FieldStorage.Yes); </code></pre> <p>When you query this, you'll need to tell Raven to send you back the index entries, by using <code>ProjectFromIndexFieldsInto</code> <a href="http://ravendb.net/docs/2.5/client-api/querying/results-transformation/project-from-index-fields-into" rel="nofollow">as described here</a>.</p> <p>Next, you need to realize that you aren't creating any single index entry that will match your query. The multimap index is creating <em>separate</em> entries in the index for each map. If you want to combine them in your results, you'll need to use an <a href="http://ravendb.net/docs/2.5/client-api/querying/intersection" rel="nofollow">intersection query</a>.</p> <p>Putting this together, your query should look like this:</p> <pre><code>var q = session.Query&lt;TradingIndex.Result, TradingIndex&gt;() .Where(g =&gt; g.Game.In(gamesIWant) &amp;&amp; g.List == TradingIndex.ListType.Tradelist &amp;&amp; g.Member != me.Id) .Intersect() .Where(g =&gt; g.Game.In(gamesITrade) &amp;&amp; g.List == TradingIndex.ListType.Wishlist &amp;&amp; g.Member != me.Id) .ProjectFromIndexFieldsInto&lt;TradingIndex.Result&gt;(); </code></pre> <p><a href="https://gist.github.com/mj1856/7284038" rel="nofollow">Full test in this GIST</a>.</p>

    1. COFor some reason your code didn't work with my data. However, after dropping all data and indexes and recreating it it did seem to work. Strange. Isn't RavenDB supposed to rebuild the index when it detects changes?

    2. COYou probably could have just *reset* the index, rather than having to drop all your data. But I'll look into that further. I wonder if Raven is considering changes to `FieldStorage` settings in determining if an index needs to be rebuilt.

    3. CORan a couple of tests, and it does appear that changes to field storage do rebuild the index. See [this GIST](https://gist.github.com/mj1856/7311049). Perhaps the index was just still rebuilding when you checked the first time?

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.
