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 indexer definition (as well as indexer execution status) when you want full assurance that no one, not even Microsoft, can decrypt them. Once you have encrypted your indexer 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 indexer definition (and indexer execution status) 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.

fieldMappings

FieldMapping[]

Defines mappings between fields in the data source and corresponding target fields in the index.

outputFieldMappings

FieldMapping[]

Output field mappings are applied after enrichment and immediately before indexing.

parameters

IndexingParameters

Parameters for indexer execution.

BlobIndexerDataToExtract

Specifies the data to extract from Azure blob storage and tells the indexer which data to extract from image content when "imageAction" is set to a value other than "none". This applies to embedded image content in a .PDF or other application, or image files such as .jpg and .png, in Azure blobs.

BlobIndexerImageAction

Determines how to process embedded images and image files in Azure blob storage. Setting the "imageAction" configuration to any value other than "none" requires that a skillset also be attached to that indexer.

BlobIndexerParsingMode

Represents the parsing mode for indexing from an Azure blob data source.

BlobIndexerPDFTextRotationAlgorithm

Determines algorithm for text extraction from PDF files in Azure blob storage.

FieldMapping

Defines a mapping between a field in a data source and a target field in an index.

FieldMappingFunction

Represents a function that transforms a value from a data source before indexing.

IndexerExecutionEnvironment

Specifies the environment in which the indexer should execute.

IndexingParameters

Represents parameters for indexer execution.

IndexingParametersConfiguration

A dictionary of indexer-specific configuration properties. Each name is the name of a specific property. Each value must be of a primitive type.

IndexingSchedule

Represents a schedule for indexer execution.

SearchError

Describes an error condition for the API.

SearchIndexer

Represents an indexer.

SearchResourceEncryptionKey

A customer-managed encryption key in Azure Key Vault. Keys that you create and manage can be used to encrypt or decrypt data-at-rest on your search service, such as indexes and synonym maps.

AzureActiveDirectoryApplicationCredentials

Credentials of a registered application created for your search service, used for authenticated access to the encryption keys stored in Azure Key Vault.

Name Type Description
applicationId

string

An AAD Application ID that was granted the required access permissions to the Azure Key Vault that is to be used when encrypting your data at rest. The Application ID should not be confused with the Object ID for your AAD Application.

applicationSecret

string

The authentication key of the specified AAD application.

BlobIndexerDataToExtract

Specifies the data to extract from Azure blob storage and tells the indexer which data to extract from image content when "imageAction" is set to a value other than "none". This applies to embedded image content in a .PDF or other application, or image files such as .jpg and .png, in Azure blobs.

Name Type Description
allMetadata

string

Extracts metadata provided by the Azure blob storage subsystem and the content-type specific metadata (for example, metadata unique to just .png files are indexed).

string

Extracts all metadata and textual content from each blob.

storageMetadata

string

Indexes just the standard blob properties and user-specified metadata.

BlobIndexerImageAction

Determines how to process embedded images and image files in Azure blob storage. Setting the "imageAction" configuration to any value other than "none" requires that a skillset also be attached to that indexer.

Name Type Description
generateNormalizedImagePerPage

string

Extracts text from images (for example, the word "STOP" from a traffic stop sign), and embeds it into the content field, but treats PDF files differently in that each page will be rendered as an image and normalized accordingly, instead of extracting embedded images. Non-PDF file types will be treated the same as if "generateNormalizedImages" was set.

generateNormalizedImages

string

Extracts text from images (for example, the word "STOP" from a traffic stop sign), and embeds it into the content field. This action requires that "dataToExtract" is set to "contentAndMetadata". A normalized image refers to additional processing resulting in uniform image output, sized and rotated to promote consistent rendering when you include images in visual search results. This information is generated for each image when you use this option.

none

string

Ignores embedded images or image files in the data set. This is the default.

BlobIndexerParsingMode

text

string

Set to text to improve indexing performance on plain text files in blob storage.

BlobIndexerPDFTextRotationAlgorithm

Determines algorithm for text extraction from PDF files in Azure blob storage.

Name Type Description
detectAngles

string

May produce better and more readable text extraction from PDF files that have rotated text within them. Note that there may be a small performance speed impact when this parameter is used. This parameter only applies to PDF files, and only to PDFs with embedded text. If the rotated text appears within an embedded image in the PDF, this parameter does not apply.

none

string

Leverages normal text extraction. This is the default.

Name Type Description
mappingFunction

FieldMappingFunction

A function to apply to each source field value before indexing.

maxFailedItemsPerBatch

integer

0

The maximum number of items in a single batch that can fail indexing for the batch to still be considered successful. -1 means no limit. Default is 0.

IndexingParametersConfiguration

A dictionary of indexer-specific configuration properties. Each name is the name of a specific property. Each value must be of a primitive type.

Name Type Default Value Description
allowSkillsetToReadFileData

boolean

False

If true, will create a path //document//file_data that is an object representing the original file data downloaded from your blob data source. This allows you to pass the original file data to a custom skill for processing within the enrichment pipeline, or to the Document Extraction skill.

dataToExtract

BlobIndexerDataToExtract

contentAndMetadata

string

Comma-delimited list of filename extensions to ignore when processing from Azure blob storage. For example, you could exclude ".png, .mp4" to skip over those files during indexing.

executionEnvironment

IndexerExecutionEnvironment

standard

Specifies the environment in which the indexer should execute.

failOnUnprocessableDocument

boolean

False

For Azure blobs, set to false if you want to continue indexing if a document fails indexing.

firstLineContainsHeaders

boolean

True

For CSV blobs, indicates that the first (non-blank) line of each blob contains headers.

imageAction

indexStorageMetadataOnlyForOversizedDocuments

boolean

False

For Azure blobs, set this property to true to still index storage metadata for blob content that is too large to process. Oversized blobs are treated as errors by default. For limits on blob size, see https://docs.microsoft.com/azure/search/search-limits-quotas-capacity.
