I have upgraded to pro
When I enable Advanced Search box, and then select post_title and _sku as my searchable fields, the search results do not filter. IE: I type in a sku I know exists but all products still show. Even tyring to search a keyword gives same results: all products shown.
When I turn off the Search From selections so that there are no selections, search by keyword does work, but entering a sku in the search field returns 0 results.
