Hello,

First of all thanks for choosing our Theme, we are glad to be you in the WoodMart WordPress family :-).

Unfortunately, there is no option in Theme Settings to set the search to work for the whole website.

You can set the search from posts, portfolio, products from WoodMart >> Header Builder >> Edit Header >> Edit Search.

Best Regards.
