Thank you for the quick response!
For the purpose of this example, the theme is twenty-twenty. I am not running a child theme.
I followed your instructions and changed the shortcode in the WooCommerce PRODUCT short description to [gallery]. It also did not expand. This tends to imply that shortcodes are not expanded in site search results for products. So the MasterStudy theme would not expand it either.
What things could be done? Does this require custom work? I have some familiarity with PHP, I just don’t know which module to look at to make a change. I would any alternatives you could suggest.
