You've got Products, each with a name and a category. A user is looking for accessories for a "camera", not actual cameras. Let's guide the user:

🔗 Playground link: filter by category

Solution

You might first try adding an equals on category within compound.filter:

    filter: [
      {
        equals: {
          path: "category",
          value: "Accessories"
        }
      }
    ]

Which leads us to this, which isn't yet working: 🔗 Playground link: filter by category not working yet

Note the surprising effect of querying a path that was not indexed specifically for that operator!

Using equals on a string field effectively requires that it be mapped as type token:

  {
    "mappings": {
      "dynamic": true,
      "fields": {
        "category": [
          {
            "type": "token"
          }
        ]
      }
    }
  }
