I'd like to create a search bar and a CTA button, so that when you insert text and press the button, it finds blog posts that contain this text.
I know Wix has a feature for that, but I'd like to develop my own in order to design the search bar the way I want to.
If anyone by any chance is ready to help me with the code, or if you have got a relevant tutorial built for beginners, that would help a lot.
The wix-search API should have the resources you need code-wise. The Velo forum may have some tips regarding Wix search.
