Hi, @Arezz. I'm happy to look into this with you! To clarify, are you searching on your storefront or within your Shopify admin? Also, can you tell me more about the additional stuff being brought up in your search that you'd like to prevent? I just want to make sure I'm giving you helpful advice going forward.
Once I have more information I can share more suggestions to help with this. The following guides on searching your Shopify admin and online store can help in the meantime.
