Hi,

I'm wanting to adjust the searched fields in the backoffice to add a reference field. I've implemented code as per https://our.umbraco.com/Documentation/Extending/Backoffice-Search/ as follows:

public class CustomUmbracoTreeSearcherFields : UmbracoTreeSearcherFields, IUmbracoTreeSearcherFields
{
    public IEnumerable<string> GetBackOfficeFields()
    {
        return new List<string>(base.GetBackOfficeFields()) { "reference" };
    }
}

Issue is I never see the GetBackOfficeFields function called, do I need to register it somewhere?

Thanks Andy
