applicationSecret	string	The authentication key of the specified AAD application.

DataSourceCredentials

Represents credentials that can be used to connect to a datasource.

Name	Type	Description
connectionString	string	The connection string for the datasource. Set to `<unchanged>` (with brackets) if you don't want the connection string updated. Set to `<redacted>` if you want to remove the connection string value from the datasource.

HighWaterMarkChangeDetectionPolicy

Defines a data change detection policy that captures changes based on the value of a high water mark column.

Name	Type	Description
@odata.type	string: #Microsoft.Azure.Search.HighWaterMarkChangeDetectionPolicy	A URI fragment specifying the type of data change detection policy.
highWaterMarkColumnName	string	The name of the high water mark column.

NativeBlobSoftDeleteDeletionDetectionPolicy

Defines a data deletion detection policy utilizing Azure Blob Storage's native soft delete feature for deletion detection.

Name	Type	Description

SearchError

Describes an error condition for the API.

Name	Type	Description
code	string	One of a server-defined set of error codes.
details	SearchError[]	An array of details about specific errors that led to this reported error.
message	string	A human-readable representation of the error.

SearchIndexerDataContainer

Represents information about the entity (such as Azure SQL table or CosmosDB collection) that will be indexed.

Name	Type	Description
name	string	The name of the table or view (for Azure SQL data source) or collection (for CosmosDB data source) that will be indexed.
query	string	A query that is applied to this data container. The syntax and meaning of this parameter is datasource-specific. Not supported by Azure SQL datasources.

SearchIndexerDataNoneIdentity

Clears the identity property of a datasource.

Name	Type	Description
@odata.type	string: #Microsoft.Azure.Search.DataNoneIdentity	A URI fragment specifying the type of identity.

SearchIndexerDataSource

Represents a datasource definition, which can be used to configure an indexer.

Name	Type	Description
@odata.etag	string	The ETag of the data source.
container	SearchIndexerDataContainer	The data container for the datasource.
credentials	DataSourceCredentials	Credentials for the datasource.

description	string	The description of the datasource.
encryptionKey	SearchResourceEncryptionKey	A description of an encryption key that you create in Azure Key Vault. This key is used to provide an additional level of encryption-at-rest for your datasource definition when you want full assurance that no one, not even Microsoft, can decrypt your data source definition. Once you have encrypted your data source definition, it will always remain encrypted. The search service will ignore attempts to set this property to null. You can change this property as needed if you want to rotate your encryption key; Your datasource definition will be unaffected. Encryption with customer-managed keys is not available for free search services, and is only available for paid services created on or after January 1, 2019.
