We have noticed that Ajax Search Pro does not search the short description for WooCommerce products. This is a critical issue for us because our +/- 2000 products all have important keywords in the short description that are now not being used as sources for the search. It also doesn’t find the SKU codes that every product has. Did I miss a setting or is there a way to include the short description and SKU fields in the search sources?
I’ve checked your search configuration and it looks like that was the problem. The search in excerpts was turned off and the “_sku” custom field was not selected: http://i.imgur.com/HEqM18k.png
