I know that this has been flagged many times before, but just wanted to point it out again.
The Search functionality is one of the biggest blockers and pain points for me and my clients ever since I started working with Prismic 2 years ago. If I have +100 articles of a custom type, the search bar doesn't help, often times it makes it even worse by hiding the document I'm looking for. So I usually have to scroll through 100 articles until I find the relevant article I'm looking for.
Even adding something as simple as searching by uid, it would improve the UX by 10 times. It could simply look like
We then extract the uid and find the specific article I'm looking for.
