In my implementation of Merchello I have got to a point where a shipment is programatically added once payment confirmation has been received.

I can see the shipment I have added in the database but I dont see it in the back end unless I manually delete the Merchello examine indexes.

I want the shipment to be immediately visible in the back end but I cant seem to programatically clear/rebuild the examine indexes from c# after adding the shipment.

So far I have tried this:

Examine.ExamineManager.Instance.IndexProviderCollection["MerchelloInvoiceIndexer"].RebuildIndex();

and this:

var IndexProvider = Examine.ExamineManager.Instance.IndexProviderCollection["MerchelloInvoiceIndexer"];

IndexProvider.DeleteFromIndex(invoice.Key.ToString());

But nether solution has worked. I would appreciate any guidance as to clear/update the index.
