# Ingest processors
|
||
|
|
|
||
|
|
Ingest processors are a core component of [ingest pipelines]({{site.url}}{{site.baseurl}}/api-reference/ingest-apis/ingest-pipelines/) because they preprocess documents before indexing. For example, you can remove fields, extract values from text, convert data formats, or append additional information.
|
||
|
|
|
||
|
|
OpenSearch provides a standard set of ingest processors within your OpenSearch installation. For a list of processors available in OpenSearch, use the [Nodes Info]({{site.url}}{{site.baseurl}}/api-reference/nodes-apis/nodes-info/) API operation:
|
||
|
|
|
||
|
|
```json
|
||
|
|
GET /_nodes/ingest?filter_path=nodes.*.ingest.processors
|
||
|
|
```
|
||
|
|
{% include copy-curl.html %}
|
||
|
|
|
||
|
|
To set up and deploy ingest processors, make sure you have the necessary permissions and access rights. See [Security plugin REST API]({{site.url}}{{site.baseurl}}/security/access-control/api/) to learn more.

Processor types and their required or optional parameters vary depending on your specific use case. See the [Ingest processors]({{site.url}}{{site.baseurl}}/api-reference/ingest-apis/ingest-processors/) section to learn more about the processor types and defining and configuring them within a pipeline.
