-```java
-// Make sure to use the Discovery v1 import!
-Authenticator authenticator = new IamAuthenticator("<iam_api_key>");
-Discovery discovery = new Discovery("2019-04-30", authenticator);
-
-//Build an empty query on an existing environment/collection
-String environmentId = "<environment_id>";
-String collectionId = "<collection_id>";
-QueryOptions queryOptions = new QueryOptions.Builder(environmentId, collectionId).build();
-QueryResponse queryResponse = discovery.query(queryOptions).execute().getResult();
