If you want to use the advance search box, then select Show Search Box from “Search &Filter” tab. It will appear a search box on your front-end table page. Now turn on “Advance Search” option from Configure page.
You can also search from a specific area. As an example, suppose you want to search only from the post title and SKU then select post_title and _sku from “Search From”. Also, you can search from other sections.
Also you can search from taxonomy as well. Set which taxonomy you want to search in.
