Extracts and summarizes information about the documents and terms in an Elasticsearch data stream or index

GET /{index}/_graph/explore

Path parameters

index string | array[string] Required

Name of the index.

Query parameters

routing string

Custom value used to route operations to a specific shard.
timeout string

Specifies the period of time to wait for a response from each shard. If no response is received before the timeout expires, the request fails and returns an error. Defaults to no timeout.

- vertices array[object] Required
  
  Contains the fields you are interested in.
  Hide vertices attributes Show vertices attributes object
  
  exclude array[string]
  
  Prevents the specified terms from being included in the results.
  
  field string Required
  
  Path to field or array of paths. Some API's support wildcards in the path to select multiple fields.
  
  include array[object]
  
  Identifies the terms of interest that form the starting points from which you want to spider out.
  
  Hide include attributes Show include attributes object
  
  boost number Required
  
  term string Required
  
  min_doc_count number
  
  Specifies how many documents must contain a pair of terms before it is considered to be a useful connection. This setting acts as a certainty threshold.
  
  shard_min_doc_count number
  
  Controls how many documents on a particular shard have to contain a pair of terms before the connection is returned for global consideration.
  
  size number
  
  Specifies the maximum number of vertex terms returned for each field.
controls object

Additional properties are allowed.

- sample_diversity object
  
  Additional properties are allowed.
  Hide sample_diversity attributes Show sample_diversity attributes object
  
  field string Required
  
  Path to field or array of paths. Some API's support wildcards in the path to select multiple fields.
  
  max_docs_per_value number Required
- sample_size number
  
  Each hop considers a sample of the best-matching documents on each shard. Using samples improves the speed of execution and keeps exploration focused on meaningfully-connected terms. Very small values (less than 50) might not provide sufficient weight-of-evidence to identify significant connections between terms. Very large sample sizes can dilute the quality of the results and increase execution times.
- timeout string
  
  A duration. Units can be nanos, micros, ms (milliseconds), s (seconds), m (minutes), h (hours) and d (days). Also accepts "0" without a unit and "-1" to indicate an unspecified value.
- use_significance boolean Required
  
  Filters associated terms so only those that are significantly associated with your query are included.
query object
