Unified Search - Return custom field

Vote:
 

Hi,

I am trying to show a custom field in a unified search results.  I can successfully add custom fields to the index based on extension methods:

SearchClient.Instance.Conventions.ForInstancesOf().IncludeField(x => x.MyGenericExtensionMethod())

I can filter on the custom field:

mySearchClient = mySearchClient.Filter(x => x.MyGenericExtensionMethod().Match("text to match"));

... but what I can't work out how to do, is return the result of the extension method into my results.  NB: I've run out of ISearchContent fields to override / project into (primarily because we have different types of searches on the site, which require different implementations of the same field to be displayed in the results, e.g. different excerpt/summary text).  I don't really understand the CustomizeProjection method which I suspect may be the answer?  

I guess worst case I can use specific elements in the SearchAuthors field for different purposes, but it seems a horrible hack.

NB: I found Per's comments in this article useful to get so far

You could retrieve the the original object when listing results.

If you do GetContentResult it's already in the cache.

If it's a page you could can do something like this:

public static PageReference PageLink(this UnifiedSearchHit hit)
{
    if (typeof(PageData).IsAssignableFrom(hit.OriginalObjectType))
    {
        PageReference pageReference = PageReference.ParseUrl(hit.Url);

        if (!PageReference.IsNullOrEmpty(pageReference))
        {
            return pageReference;
        }
                
        object internalObject;

        if (Global.UrlRewriteProvider.ConvertToInternal(new UrlBuilder(hit.Url), out internalObject))
        {
            pageReference = internalObject as PageReference;

            if (!PageReference.IsNullOrEmpty(pageReference))
            {
                return pageReference;
            }
        }
    }

    return PageReference.EmptyReference;
}

Thanks Johan, that's useful especially the cache advice.

Or just call the OriginalObjectGetter:

public static T GetOriginalObject<T>(this UnifiedSearchHit hit)
{
    if (hit.OriginalObjectGetter != null)
    {
        var original = hit.OriginalObjectGetter.Invoke();

        if (original is T)
        {
            return (T)original;
        }
    }

    return default(T);
}

Then you can:

var content = hit.GetOriginalObject<YourPageDataPage>();
