Description

Enhance search as URL parameter Also making it DRY, so it reduces the number of lines overall

[Malix-Labs]

Tables are broken on 2 out of 3 pages, reverting to draft

It works perfectly for collection though : https://malix-labs.github.io/devcontainers.github.io/collections?search=test

I need help by someone knowing the codebase, I don't seem to succeed understanding how it would be supposed to work and fetch data

Again, collections work with perfect UX, but not features or template (see https://malix-labs.github.io/devcontainers.github.io/collections?search=test)
