Example: Enrich your data by matching a value to a range

A range enrich policy uses a term query to match a number, date, or IP address in incoming documents to a range of the same type in the enrich index. Matching a range to a range is not supported.

The following example creates a range enrich policy that adds a descriptive network name and responsible department to incoming documents based on an IP address. It then adds the enrich policy to a processor in an ingest pipeline.

Use the create index API with the appropriate mappings to create a source index.

PUT /networks
{
  "mappings": {
    "properties": {
      "range": { "type": "ip_range" },
      "name": { "type": "keyword" },
      "department": { "type": "keyword" }
    }
  }
}

The following index API request indexes a new document to that index.

PUT /networks/_doc/1?refresh=wait_for
{
  "range": "10.100.0.0/16",
  "name": "production",
  "department": "OPS"
}

Use the create enrich policy API to create an enrich policy with the range policy type. This policy must include:

• One or more source indices
• A match_field, the field from the source indices used to match incoming documents
• Enrich fields from the source indices you’d like to append to incoming documents

Since we plan to enrich documents based on an IP address, the policy’s match_field must be an ip_range field.

PUT /_enrich/policy/networks-policy
{
  "range": {
    "indices": "networks",
    "match_field": "range",
    "enrich_fields": ["name", "department"]
  }
}

Use the execute enrich policy API to create an enrich index for the policy.

POST /_enrich/policy/networks-policy/_execute?wait_for_completion=false

Use the create or update pipeline API to create an ingest pipeline. In the pipeline, add an enrich processor that includes:

• Your enrich policy.
• The field of incoming documents used to match documents from the enrich index.
• The target_field used to store appended enrich data for incoming documents. This field contains the match_field and enrich_fields specified in your enrich policy.

PUT /_ingest/pipeline/networks_lookup
{
  "processors" : [
    {
      "enrich" : {
        "description": "Add 'network' data based on 'ip'",
        "policy_name": "networks-policy",
        "field" : "ip",
        "target_field": "network",
        "max_matches": "10"
      }
    }
  ]
}

Use the ingest pipeline to index a document. The incoming document should include the field specified in your enrich processor.

PUT /my-index-000001/_doc/my_id?pipeline=networks_lookup
{
  "ip": "10.100.34.1"
}

To verify the enrich processor matched and appended the appropriate field data, use the get API to view the indexed document.

GET /my-index-000001/_doc/my_id

The API returns the following response:

{
  "_index" : "my-index-000001",
  "_id" : "my_id",
  "_version" : 1,
  "_seq_no" : 0,
  "_primary_term" : 1,
  "found" : true,
  "_source" : {
    "ip" : "10.100.34.1",
    "network" : [
      {
        "name" : "production",
        "range" : "10.100.0.0/16",
        "department" : "OPS"
      }
    ]
  }
}
