Executes a "search-as-you-type" query consisting of a partial text input (three character minimum). It returns matching text found in suggester-aware fields. Azure Cognitive Search looks for matching values in fields that are predefined in a Suggester. For example, if you enable suggestions on a city field, typing "sea" produces documents containing "Seattle", "Sea Tac", and "Seaside" (all actual city names) for that field. Suggestions

public virtual System.Threading.Tasks.Task<Azure.Response<Azure.Search.Documents.Models.SuggestResults<T>>> SuggestAsync<T> (string searchText, string suggesterName, Azure.Search.Documents.SuggestOptions options = default, System.Threading.CancellationToken cancellationToken = default);

Type Parameters

T

The .NET type that maps to the index schema. Instances of this type can be retrieved as documents from the index.

searchText: String

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

suggesterName: String

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

options: SuggestOptions

Options for filtering, sorting, and other suggestions query behaviors.

cancellationToken: CancellationToken

Optional CancellationToken to propagate notifications that the operation should be canceled.

Task<Response<SuggestResults<T>>>

Remarks

Suggest and SuggestAsync methods support mapping of search field types to .NET types via the type parameter T. You can provide your own type T or use the dynamic SearchDocument. See GetDocumentAsync<T>(String, GetDocumentOptions, CancellationToken) for more details on the type mapping.
