URI Parameters

Name In Required Type Description
endpoint
path True

string

The endpoint URL of the search service.

indexName
path True

string

The name of the index.

api-version
query True

Client Api Version.

search
query True

string

The search text to use to suggest documents. Must be at least 1 character, and no more than 100 characters.

suggesterName
query True

string

The name of the suggester as specified in the suggesters collection that's part of the index definition.

$filter
query

string

An OData expression that filters the documents considered for suggestions.

$orderby
query

string[]

The list of OData $orderby expressions by which to sort the results. Each expression can be either a field name or a call to either the geo.distance() or the search.score() functions. Each expression can be followed by asc to indicate ascending, or desc to indicate descending. The default is ascending order. Ties will be broken by the match scores of documents. If no $orderby is specified, the default sort order is descending by document match score. There can be at most 32 $orderby clauses.

$select
query

string[]

The list of fields to retrieve. If unspecified, only the key field will be included in the results.

query

integer

int32

The number of suggestions to retrieve. The value must be a number between 1 and 100. The default is 5.

fuzzy
query

boolean

A value indicating whether to use fuzzy matching for the suggestions query. Default is false. When set to true, the query will find terms even if there's a substituted or missing character in the search text.
