I see you can do it with a tag, or [hidden] with products and collections per the documentation. I tried [hidden] on the page title and it still added it to the index.
Thanks for reaching us! I am Alex, developer at Algolia, working on Shopify, nice to meet you!
We indeed do not provide this feature yet, but I added it to our backlog and we will take care of it!
Thanks for this helpful feedback!
Hello @ruffwear ,
