Parameters

requests
type: list of request object
Required

A list of request objects to execute.

requests ➔ request object

indexName
type: string
Required

The name of the target index.

threshold
type: number
Optional

Threshold for the recommendations confidence score (between 0 and 100). Only recommendations with a greater score are returned.

maxRecommendations
type: number
Optional

The number of recommendations to retrieve. Depending on the available recommendations and the other request parameters, the actual number of hits may be lower than that. If maxRecommendations isn’t provided or set to 0, all matching recommendations are returned, and no fallback request is performed.

facetName
type: string
Required

The facet attribute to get recommendations for.

Response

This section shows the JSON response returned by the API. Each API client encapsulates this response inside objects specific to the programming language, so that the actual response might be different. You can view the response by using the getLogs method. Don’t rely on the order of attributes in the response, as JSON doesn’t guarantee the ordering of keys in objects.

results ➔ result

The results object contains the same hits object as the one of the search method. The results do not contain objectID as they do not refer to a specific item. Each result also includes the following additional field:

Field Description
_score
number

The confidence score of the recommended facet value, the closer it’s to 100, the more relevant.
