    host: "localhost",
    port: "8108",
    protocol: "http",
    apiKey: "dev-api-key"
  },
  timeoutSeconds: 2
});

client
  .collections("profiles")
  .delete()
  .catch(() => {});

client.collections().create({
  name: "profiles",

constructor(props) {
            super(props);

            this.client = new Typesense.Client({
                masterNode: {
                    host: 'search.datenanfragen.de',
                    port: '443',
