Joomla Virtuemart Product search plugin not finding products

The vmxsearch.plugin that comes with Virtuemart to integrate product search into the normal joomla website search works great once its configured. Some products may not show in the search results.

The main cause for this is if the product is out of stock. In my case I had a -2 in the stock amount for the products that were not showing.

Change this by going into the admin->virtuemart->product list-> edit product and change the stock on the Product Status Tab.
