Using a prefix query
The prefix query is used when only the starting part of a term is known. It allows for the completion of truncated or partial terms.
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 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 command, which is available in the online code.
How to do it...
To execute a prefix query, we will perform the following steps:
- We execute a
prefixquery from the command line, as follows:POST /mybooks/_search { "query": { "prefix": { "uuid"...
