Enrich Processoredit

The enrich processor can enrich documents with data from another index. See enrich data section for more information about how to set this up.

Table 44. Enrich Options

Name Required Default Description

policy_name

yes

-

The name of the enrich policy to use.

field

yes

-

The field in the input document that matches the policies match_field used to retrieve the enrichment data. Supports template snippets.

target_field

yes

-

Field added to incoming documents to contain enrich data. This field contains both the match_field and enrich_fields specified in the enrich policy. Supports template snippets.

ignore_missing

no

false

If true and field does not exist, the processor quietly exits without modifying the document

override

no

true

If processor will update fields with pre-existing non-null-valued field. When set to false, such fields will not be touched.

max_matches

no

1

The maximum number of matched documents to include under the configured target field. The target_field will be turned into a json array if max_matches is higher than 1, otherwise target_field will become a json object. In order to avoid documents getting too large, the maximum allowed value is 128.

shape_relation

no

INTERSECTS

A spatial relation operator used to match the geo_shape of incoming documents to documents in the enrich index. This option is only used for geo_match enrich policy types. The geo_shape strategy mapping parameter determines which spatial relation operators are available. See Spatial Relations for operators and more information.

if

no

-

Conditionally execute this processor.

on_failure

no

-

Handle failures for this processor. See Handling Failures in Pipelines.

ignore_failure

no

false

Ignore failures for this processor. See Handling Failures in Pipelines.
