I'm using Sitecore 8.0 update 5. I'm a having a strange issue with Lucene.

I'm trying to update a product in the index with the following code:

var tempItem = (SitecoreIndexableItem)item;

         ContentSearchManager.GetIndex("sitecore_products_index").Refresh(tempItem);

Instead of an update, the code creates a new product entry in the index with no data (blank). If I debug, I can see the uniqueid is matching, so I'm not sure what is causing this behavior. If I simply do a '.Rebuild()', it refreshes the index with the new product, but I don't want to do that for one product change.

In addition to this, OnPublishEndAsync wasn't working either. Products change and the index won't refresh.

I found this bug fix, but it didn't seem to work for me: https://kb.sitecore.net/articles/992608

Thanks for any help!
