== Client
|

|
|
|

|
|
Obtaining an elasticsearch Groovy `GClient` (a `GClient` is a simple
|
||
|
|
wrapper on top of the Java `Client`) is simple. The most common way to
|
||
|
|
get a client is by starting an embedded `Node` which acts as a node
|
||
|
|
within the cluster.

=== Node Client
|
||
|
|
|
||
|
|
A Node based client is the simplest form to get a `GClient` to start
|
||
|
|
executing operations against elasticsearch.

Since elasticsearch allows to configure it using JSON based settings,
|
||
|
|
the configuration itself can be done using a closure that represent the
|

|
JSON:
