Elasticsearch supports the ability to run search and aggregation requests across multiple | ||
clusters using a module called _cross cluster search_. | ||
{es} supports the ability to run search and aggregation requests across multiple | ||
clusters using a module called _{ccs}_. | ||
|
||
In order to take advantage of cross cluster search, you must configure your Elasticsearch | ||
clusters accordingly. Review the corresponding Elasticsearch | ||
{ref}/modules-cross-cluster-search.html[documentation] before attempting to use cross cluster | ||

|
||
Once your Elasticsearch clusters are configured for cross cluster search, you can create | ||
specific index patterns in Kibana to search across the clusters of your choosing. Using the | ||
same syntax that you'd use in a raw cross cluster search request in Elasticsearch, create your | ||
index pattern in Kibana with the convention `<cluster-names>:<pattern>`. | ||

same syntax that you'd use in a raw {ccs} request in {es}, create your | ||
index pattern in {kib} with the convention `<cluster-names>:<pattern>`. | ||
|
||
For example, if you want to query logstash indices across two of the Elasticsearch clusters | ||
that you set up for cross cluster search, which were named `cluster_one` and `cluster_two`, | ||
you would use `cluster_one:logstash-*,cluster_two:logstash-*` as your index pattern in Kibana. | ||
For example, if you want to query {ls} indices across two of the {es} clusters | ||
that you set up for {ccs}, which were named `cluster_one` and `cluster_two`, | ||
you would use `cluster_one:logstash-*,cluster_two:logstash-*` as your index pattern in {kib}. | ||

Just like in raw search requests in Elasticsearch, you can use wildcards in your cluster names | ||
to match any number of clusters, so if you wanted to search logstash indices across any | ||

clusters named `cluster_foo`, `cluster_bar`, and so on, you would use `cluster_*:logstash-*` | ||
as your index pattern in Kibana. | ||

If you want to query across all Elasticsearch clusters that have been configured for cross | ||

*Remote Clusters* helps you manage remote clusters for use with | ||
