Executing a standard search

In the previous recipe, we learned how to build queries. In this recipe, we will execute a query to retrieve some documents.

You need an up-and-running Elasticsearch installation, as we described in the Downloading and installing Elasticsearch recipe in Chapter 1, Getting Started.

A Maven tool or an IDE that natively supports it for Java programming, such as Visual Studio Code, Eclipse, or IntelliJ IDEA, must be installed.

The code for this recipe is in the ch13/elasticsearch-java-client directory and the referred class is the QueryExample.
