Hi @Emiway collections are not a type for the standard search form.
https://shopify.dev/docs/storefronts/themes/navigation-search/search#query-parameters
and the products themselves do not show up for the relevant search as well.
For searching collections that would require either:
- search-apps with that behavior
- or since you only a handful of collection a theme customization that when products are returned the collections those products are in are checked and displayed.
the drawer is using a predictive-search component to get suggestions and not just search

Search page uses a different system for queried and rendered results

If using a search app like shopifys search-and-discovery app it may need configuration.
