So, I have my object like the following:

public class CrawledItem
{
public string Url { get; set; }
public string Title { get; set; }
public string Text { get; set; }
public DateTime Published { get; set; }
public List<Keyword> Keywords { get; set; }
}

public class Keyword
{
public string Title { get; set; }
public float Weight { get; set; }
}

 I'm using a custom crawler to add objects like the above to a Find Index..

I am running into issues on have I can leverage this object in a Find Search Query... I was hoping to be able to return items inside "Keywords" as facets, but can't seem to work out how I would do this..

Can anyone suggest a better / another way I could use Find on an object like the above?

Thanks
Danny
