Using a query string query
In the previous recipes, we looked at several types of queries that use text to match the results. The query string query is a special type of query that allows us to define complex queries by mixing the field rules.
It uses the Lucene query parser to parse text to complex queries.
Getting ready
You will need an up-and-running Elasticsearch installation, as described in the Downloading and installing Elasticsearch recipe of Chapter 1, Getting Started.
To execute the commands, any HTTP client can be used, such as Curl (https://curl.haxx.se/), Postman (https://www.getpostman.com/), or similar. I suggest you use the Kibana console as it provides code completion and better character escaping for Elasticsearch.
To correctly execute the following commands, you will need an index populated with the ch04/populate_kibana.txt command, which is available in the online code.
