title: Dynamic fields with Thinking Sphinx
body: <p>I'm building an application where I have products and categories. Category has_many properties and each property has a list of possible values. After a category is set to the product all properties show up in the form and the user can set that property to one of the properties possible values.</p>
  
  <p>My question is:</p>
  
  <p>Is it possible for Thinking Sphinx to filter the products through a property and property value ex:</p>
  
  <pre><code>:with =&gt; {:property_id =&gt; property_value}
  </code></pre>
  
  <p>If it's possible, what is the best way to implement this? If not is there any other library  out there to solve this problem?</p>
  
  <p>Thanks</p>
