Is it possible to deep filter results

[lburns-civiconnect]

As an example from my restaurant app, I have two collections: Menu Items and Allergens. Allergens is a many-1 relationship with Menu Items. I want to be able to fuzzy search Menu Items on the "name" field, while filtering for allergens. E.x. Give me "burgers" that don't contain "gluten".

The structure of my object would be:

{
  id: 1
  name: "hamburger"
  contains: [
    {
      id: 2,
      AllergenLabel: "Gluten",
     ...
    },
    ...
  ],
  ...
}

The regular Strapi API supports this by doing filters[contains][AllergenLabel][$ne]=Gluten
When I try the fuzzy search scoped filtering like filters[menu-items][contains][AllergenLabel][$ne]=Gluten it doesnt work.

This also looks to be an open issue in Strapi where deep filtering specifically on a negative ($ne, $notIn, etc.) doesn't work.
