Hi Perrie, Yes, I’m happy to help you. I have responded to your email. 
Topic summary
Main issue: The theme’s search bar isn’t returning products. Shopify indicated the cause is a coding problem within the theme affecting product search functionality.
Support offered: A helper requested private access to review the theme code, asking for the store URL and collaborator access via email. Instructions point to granting access through Settings → Users and permissions; a screenshot is provided to guide this step.
Contact details: The helper shared an email address (wangsiqi@shinetechsoftware.com) to receive access details and begin investigation. They noted they will share findings before applying any fixes.
Additional reports: Another merchant reported the same search issue and reached out for assistance. The helper confirmed they responded via email.
Status: No in-thread technical resolution yet. Next steps are for affected stores to grant collaborator access and share details so the theme code can be reviewed and the search functionality fixed privately.
