Using a match query
Elasticsearch provides a helper to build complex span queries that depend on simple preconfigured settings. This helper is called match query.
Getting ready
You need an up-and-running Elasticsearch installation, as we described in the Downloading and installing Elasticsearch recipe in Chapter 1, Getting Started.
To execute these 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 commands, which is available in the online code.
How to do it...
To execute match queries, we will perform the following steps:
- The standard usage of a match query simply requires the field name and the query text. Consider the following example:
POST /mybooks/_search
{
"query": {
"match": {
...
