 # Elasticsearch (Bulk API)
 
-The **elasticsearch** input plugin handles both Elasticsearch and OpenSearch Bulk API requests.
+The _Elasticsearch_ input plugin handles both Elasticsearch and OpenSearch Bulk API requests.
 
-## Configuration Parameters
+## Configuration parameters
 
 The plugin supports the following configuration parameters:
 
 | Key | Description | Default value |
 | :--- | :--- | :--- |
-| buffer\_max\_size | Set the maximum size of buffer. | 4M |
-| buffer\_chunk\_size | Set the buffer chunk size. | 512K |
-| tag\_key | Specify a key name for extracting as a tag. | `NULL` |
-| meta\_key | Specify a key name for meta information. | "@meta" |
-| hostname | Specify hostname or FQDN. This parameter can be used for "sniffing" (auto-discovery of) cluster node information. | "localhost" |
-| version  | Specify Elasticsearch server version. This parameter is effective for checking a version of Elasticsearch/OpenSearch server version. | "8.0.0" |
-| threaded | Indicates whether to run this input in its own [thread](../../administration/multithreading.md#inputs). | `false` |
-
-**Note:** The Elasticsearch cluster uses "sniffing" to optimize the connections between its cluster and clients.

+The Elasticsearch cluster uses "sniffing" to optimize the connections between its cluster and clients.
 Elasticsearch can build its cluster and dynamically generate a connection list which is called "sniffing".
 The `hostname` will be used for sniffing information and this is handled by the sniffing endpoint.
