[[v0_90]]
|
|
== Elasticsearch 0.90.* and earlier
|
|
|
|
The current version of the client supports the Elasticsearch 1.0 branch by
|
|
default, which is not backwards compatible with the 0.90 branch.
|
|
|
|
If you need to talk to a version of Elasticsearch before 1.0.0,
|
|
please use `Elasticsearch::Client::0_90::Direct` as follows:
|
|
|
|
[source,perl]
|
|
------------------------------------
|
|
$es = Elasticsearch->new(
|
|
client => '0_90::Direct'
|
|
);
|
