Retrieving search pipelines

To retrieve the details of an existing search pipeline, use the Search Pipeline API.

To view all search pipelines, use the following request:

GET /_search/pipeline

{% include copy-curl.html %}

The response contains the pipeline that you set up in the previous section:

Response

{: .text-delta}

{
  "my_pipeline" : {
    "request_processors" : [
      {
        "filter_query" : {
          "tag" : "tag1",
          "description" : "This processor is going to restrict to publicly visible documents",
          "query" : {
            "term" : {
              "visibility" : "public"
            }
          }
        }
      }
    ]
  }
}

To view a particular pipeline, specify the pipeline name as a path parameter:

GET /_search/pipeline/my_pipeline

{% include copy-curl.html %}

You can also use wildcard patterns to view a subset of pipelines, for example:

GET /_search/pipeline/my*

{% include copy-curl.html %}
