Overloads
| SearchAsync(IDocumentsOperations, String, SearchParameters, SearchRequestOptions, CancellationToken) |
Searches for documents in the search index. https://docs.microsoft.com/rest/api/searchservice/Search-Documents |
| SearchAsync<T>(IDocumentsOperations, String, SearchParameters, SearchRequestOptions, CancellationToken) |
Searches for documents in the search index. https://docs.microsoft.com/rest/api/searchservice/Search-Documents |
SearchAsync(IDocumentsOperations, String, SearchParameters, SearchRequestOptions, CancellationToken)

Public Function SearchAsync (operations As IDocumentsOperations, searchText As String, Optional searchParameters As SearchParameters = Nothing, Optional searchRequestOptions As SearchRequestOptions = Nothing, Optional cancellationToken As CancellationToken = Nothing) As Task(Of DocumentSearchResult(Of Document))Parameters
- operations
- IDocumentsOperations
The operations group for this extension method.
- searchText
- String
A full-text search query expression; Use null or "*" to match all documents. See https://docs.microsoft.com/rest/api/searchservice/Simple-query-syntax-in-Azure-Search for more information about search query syntax.
- searchParameters
- SearchParameters
Parameters to further refine the search query.
- searchRequestOptions
- SearchRequestOptions
Additional parameters for the operation
- cancellationToken
- CancellationToken
The cancellation token.
Returns
Response containing the documents matching the query.
Remarks
The non-generic overloads of the Search, SearchAsync, and SearchWithHttpMessagesAsync 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.
If Azure Cognitive Search can't include all results in a single response, the response returned will include a continuation token that can be passed to ContinueSearch to retrieve more results. See DocumentSearchResult.ContinuationToken for more information.
Applies to
SearchAsync<T>(IDocumentsOperations, String, SearchParameters, SearchRequestOptions, CancellationToken)
Searches for documents in the search index. https://docs.microsoft.com/rest/api/searchservice/Search-Documents
public static System.Threading.Tasks.Task<Microsoft.Azure.Search.Models.DocumentSearchResult<T>> SearchAsync<T> (this Microsoft.Azure.Search.IDocumentsOperations operations, string searchText, Microsoft.Azure.Search.Models.SearchParameters searchParameters = default, Microsoft.Azure.Search.Models.SearchRequestOptions searchRequestOptions = default, System.Threading.CancellationToken cancellationToken = default);static member SearchAsync : Microsoft.Azure.Search.IDocumentsOperations * string * Microsoft.Azure.Search.Models.SearchParameters * Microsoft.Azure.Search.Models.SearchRequestOptions * System.Threading.CancellationToken -> System.Threading.Tasks.Task<Microsoft.Azure.Search.Models.DocumentSearchResult<'T>><Extension()>
Public Function SearchAsync(Of T) (operations As IDocumentsOperations, searchText As String, Optional searchParameters As SearchParameters = Nothing, Optional searchRequestOptions As SearchRequestOptions = Nothing, Optional cancellationToken As CancellationToken = Nothing) As Task(Of DocumentSearchResult(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.
- searchText
- String
A full-text search query expression; Use null or "*" to match all documents. See https://docs.microsoft.com/rest/api/searchservice/Simple-query-syntax-in-Azure-Search for more information about search query syntax.
- searchParameters
- SearchParameters
Parameters to further refine the search query.
- searchRequestOptions
- SearchRequestOptions
Additional parameters for the operation
- cancellationToken
- CancellationToken
The cancellation token.
Returns
Response containing the documents matching the query.
Remarks
The generic overloads of the Search, SearchAsync, and SearchWithHttpMessagesAsync methods support mapping of 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.
If Azure Cognitive Search can't include all results in a single response, the response returned will include a continuation token that can be passed to ContinueSearch to retrieve more results. See DocumentSearchResult.ContinuationToken for more information.
