Customise Hits via a Resolver

1. Add to the schema and update the type that has been configured as the hitTypeName. Normally this would be ResultHit. Below is an example of adding an additional field in Hit in the schema

    type ResultHit implements SKHit {
      id: ID!
      fields: ResultFields
      exampleCustomField: String   // example field addition
    }

see an example

Then provide a resolver for the field. See ResultsResolver for what can be provided.

  resolvers: withSearchkitResolvers({
    ResultHit: {
      exampleCustomField: ({
        id, // id contents
        rawHit // the raw ES hit contents
        }) => `Example Return Value for ${id}`
    }
  }),

see an example

then with a GQL query like below

query {
  results {
    hits {
      items {
        ... on ResultHit {
          id
          exampleCustomField
        }
      }
    }
  }
}

will call the exampleCustomField resolver for each hit item. The parent object (passed as an argument) contains the HitFields values. The return value is what will be provided in the response.

{
  "data": {
    "results": {
      "hits": {
        "items": [
          {
            "id": "tt0111161",
            "exampleCustomField": "Example Return Value for tt0111161"
          }
        ]
      }
    }
  }
}
