Index settings are those settings that apply to a single index. Such settings will start with index.. The exception to that rule is number_of_shards and number_of_replicas, which also exist in the form of index.number_of_shards and index.number_of_replicas. As the name suggests, index-level setting...

You can apply the same change shown in the Index Settings example to all existing indices with one request, or even a subset of them: PUT /*/_settings { "index": { "indexing.slowlog.threshold.index.warn": "1s", "search.slowlog.threshold": { ...

Example uses basic HTTP, which translate easily to cURL and other HTTP applications. They also match the Sense syntax, which will be renamed to Console in Kibana 5.0. Note: The example inserts <#> to help draw attention to parts. Those should be removed if you copy it! PUT /my_index <1&gt...
