ElasticGraph Query API: String Prefix Filtering

Try these example queries by visiting the GraphiQL UI after booting locally.

$ curl -s https://block.github.io/elasticgraph/dc.yml | docker compose -f - up --pull always

ElasticGraph offers a predicate to support string prefix filtering:

startsWith: Matches documents using prefix filtering.
When null is passed, matches all documents.

Here’s a basic example:

query ArtistsPrefixedWithThe {
  artists(filter: {
    name: {
      startsWith: {
        anyPrefixOf: ["The "]
      }
    }
  }) {
    edges {
      node {
        name
      }
    }
  }
}

By default, prefix searching is case-sensitive. To make it case-insensitive, pass ignoreCase: true:

query ArtistsPrefixedWithTheCaseInsensitive {
  artists(filter: {
    name: {
      startsWith: {
        anyPrefixOf: ["the "]
        ignoreCase: true
      }
    }
  }) {
    edges {
      node {
        name
      }
    }
  }
}
