Public Function GetAsync (operations As IDocumentsOperations, key As String, Optional selectedFields As IEnumerable(Of String) = Nothing, Optional searchRequestOptions As SearchRequestOptions = Nothing, Optional cancellationToken As CancellationToken = Nothing) As Task(Of Document)Parameters
- operations
- IDocumentsOperations
The operations group for this extension method.
- key
- String
The key of the document to retrieve; See https://docs.microsoft.com/rest/api/searchservice/Naming-rules for the rules for constructing valid document keys.
- selectedFields
- IEnumerable<String>
List of field names to retrieve for the document; Any field not retrieved will be missing from the returned document.
- searchRequestOptions
- SearchRequestOptions
Additional parameters for the operation
- cancellationToken
- CancellationToken
The cancellation token.
Returns
The requested document.
Remarks
The non-generic overloads of the Get, GetAsync, and GetWithHttpMessagesAsync methods make a best-effort attempt to map JSON types in the response payload to .NET types. See GetWithHttpMessagesAsync(String, IEnumerable<String>, SearchRequestOptions, Dictionary<String,List<String>>, CancellationToken) for more information.
Applies to
GetAsync<T>(IDocumentsOperations, String, IEnumerable<String>, SearchRequestOptions, CancellationToken)
Retrieves a document from the search index. https://docs.microsoft.com/rest/api/searchservice/Lookup-Document
public static System.Threading.Tasks.Task<T> GetAsync<T> (this Microsoft.Azure.Search.IDocumentsOperations operations, string key, System.Collections.Generic.IEnumerable<string> selectedFields = default, Microsoft.Azure.Search.Models.SearchRequestOptions searchRequestOptions = default, System.Threading.CancellationToken cancellationToken = default);static member GetAsync : Microsoft.Azure.Search.IDocumentsOperations * string * seq<string> * Microsoft.Azure.Search.Models.SearchRequestOptions * System.Threading.CancellationToken -> System.Threading.Tasks.Task<'T><Extension()>
Public Function GetAsync(Of T) (operations As IDocumentsOperations, key As String, Optional selectedFields As IEnumerable(Of String) = Nothing, Optional searchRequestOptions As SearchRequestOptions = Nothing, Optional cancellationToken As CancellationToken = Nothing) As Task(Of T)Type Parameters
- T
The CLR type that maps to the index schema. Instances of this type can be retrieved as documents from the index.
Parameters
- operations
- IDocumentsOperations
The operations group for this extension method.
- key
- String
The key of the document to retrieve; See https://docs.microsoft.com/rest/api/searchservice/Naming-rules for the rules for constructing valid document keys.
- selectedFields
- IEnumerable<String>
List of field names to retrieve for the document; Any field not retrieved will have null or default as its corresponding property value in the returned object. All retrievable fields are included in the result by default.
- searchRequestOptions
- SearchRequestOptions
Additional parameters for the operation
- cancellationToken
- CancellationToken
The cancellation token.
Returns
The requested document.
Remarks
The generic overloads of the Get, GetAsync, and GetWithHttpMessagesAsync methods support mapping of Azure Search field types to .NET types via the type parameter T. See GetWithHttpMessagesAsync<T>(String, IEnumerable<String>, SearchRequestOptions, Dictionary<String,List<String>>, CancellationToken) for more details on the type mapping.
