Executing a standard search

In the previous recipe, we have seen how to build queries; in this recipe we can execute a query to retrieve some documents.

Getting ready

You need an up-and-running Elasticsearch installation as we described in the Downloading and installing Elasticsearch recipe in the Chapter 2, Downloading and Setup.

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

The code for this recipe is in the chapter_14/nativeclient directory and the referred class is the QueryExample.

How to do it...

To execute a standard query, we will perform the following steps:

1. We need to import QueryBuilders to create the query:

           import static org.elasticsearch.index.query.QueryBuilders.*; 
   

2. We can create an index and populate it with some data:

           String index = "mytest"; 
           String type = "mytype"; 
           QueryHelper qh = new QueryHelper(); 
           qh.populateData(index, type); 
       ...
