Using the search template

Elasticsearch provides the capability of providing a template and some parameters to fill it. This functionality is very useful because it allows you to manage the query templates stored in the .scripts index and also allows you to change them without changing the application code.

Ever wonder why speech recognition systems don't understand the Scottish accent, or what would happen if an astronaut only ate mac 'n' cheese, or other spurious reflections you'd have at a bar?
