About this method

Create or update a single synonym on an index.

Whether you create or update a synonym, you must specify a unique objectID. If the objectID is not found in the index, the method will automatically create a new synonym.

Each synonym has a single type.

Each type consists of a unique set of attributes

Create/Update a placeholder synonym

To create placeholders, enclose the desired terms in angle brackets in the records. Consider this record:

1

{
  "address": "589 Howard <Street>"
}

    'st'
  ]
], [
  'forwardToReplicas' => true
]);

Parameters

objectID
type: string
Required

Must be unique. It can contain any character, and be of unlimited length.

With this method, you either create a new synonym or update an existing one. In both cases, you must specify an objectID. When the objectID is not found in the index, it will create a new synonym; otherwise, it will be an update.

Note that for some languages, this parameter is duplicated in the synonym object.

synonym
Required

A synonym object with only one type (see param below). Each type consists of a unique set of attributes.

forwardToReplicas
type: boolean
default: false
optional

By default, this method applies only to the specified index. By making this true, the method will also send the synonym to all replicas. Thus, if you want to forward your synonyms to replicas you will need to specify that.
