    <p>In my project I'm trying to implement Faceted search using Linq. I don't want to use Solr, Lucene, etc...</p> <p>My DB:</p> <p><strong>products</strong></p> <pre><code>+----+------+ | id | name | +----+------+ | 1 | prod1| +----+------+ | 2 | prod2| +----+------+ </code></pre> <p><strong>attributes</strong></p> <pre><code>+----+--------+---------+ | id | name | alias | +----+--------+---------+ | 1 | Weight | weight | +----+--------+---------+ | 2 | Height | height | +----+--------+---------+ </code></pre> <p><strong>values</strong></p> <pre><code>+----+---------------+---------+---------+ | id | attribute_id | value | alias | +----+---------------+---------+---------+ | 1 | 1 | 10 g | 10m | +----+---------------+---------+---------+ | 2 | 1 | 20 g | 20m | +----+---------------+---------+---------+ | 3 | 2 | 10 m | 10m | +----+---------------+---------+---------+ | 4 | 2 | 20 m | 20m | +----+---------------+---------+---------+ </code></pre> <p><strong>products_values</strong></p> <pre><code>+---------------+---------+ | product_id | value_id| +---------------+---------+ | 1 | 1 | +---------------+---------+ | 1 | 2 | +---------------+---------+ | 1 | 3 | +---------------+---------+ | 2 | 1 | +---------------+---------+ </code></pre> <p>Query for select, e.g. :<code>site.com/filter/weight=10g_20g;height=10h/</code></p> <p>POCO model for filter:</p> <pre><code>public class Filter { public string Attribute { get; set; } public IEnumerable&lt;Value&gt; Values{ get; set; } } </code></pre> <p>This model using for the custom model binding.</p> <p>But from now, having filled filter model, I don't know how implement select products and select "active" values in filter (with count enabled products). Populating filter and products table must be separated? Or, may be in single action? I'm glad to see step by step guide to implement faceted search using Linq.</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.
