describe-index

Description

Describes an existing Amazon Kendra index.

See also: AWS API Documentation

See ‘aws help’ for descriptions of global parameters.

Synopsis

  describe-index
--id <value>
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]

Options

--id (string)

The identifier of the index to describe.

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

Output

Name -> (string)

The name of the index.

Id -> (string)

The identifier of the index.

Edition -> (string)

The Amazon Kendra edition used for the index. You decide the edition when you create the index.

RoleArn -> (string)

The Amazon Resource Name (ARN) of the IAM role that gives Amazon Kendra permission to write to your Amazon Cloudwatch logs.

ServerSideEncryptionConfiguration -> (structure)

The identifier of the KMScustomer master key (CMK) that is used to encrypt your data. Amazon Kendra doesn’t support asymmetric CMKs.

KmsKeyId -> (string)

The identifier of the KMS key. Amazon Kendra doesn’t support asymmetric keys.

Status -> (string)

The current status of the index. When the value is ACTIVE , the index is ready for use. If the Status field value is FAILED , the ErrorMessage field contains a message that explains why.

Description -> (string)

The description for the index.

CreatedAt -> (timestamp)

The Unix datetime that the index was created.

UpdatedAt -> (timestamp)

The Unix datetime that the index was last updated.

DocumentMetadataConfigurations -> (list)

Configuration settings for any metadata applied to the documents in the index.

(structure)

Specifies the properties of a custom index field.

Name -> (string)

The name of the index field.

Type -> (string)

The data type of the index field.

Relevance -> (structure)

Provides manual tuning parameters to determine how the field affects the search results.

Freshness -> (boolean)

Indicates that this field determines how “fresh” a document is. For example, if document 1 was created on November 5, and document 2 was created on October 31, document 1 is “fresher” than document 2. You can only set the Freshness field on one DATE type field. Only applies to DATE fields.

Importance -> (integer)

The relative importance of the field in the search. Larger numbers provide more of a boost than smaller numbers.

Duration -> (string)

Specifies the time period that the boost applies to. For example, to make the boost apply to documents with the field value within the last month, you would use “2628000s”. Once the field value is beyond the specified range, the effect of the boost drops off. The higher the importance, the faster the effect drops off. If you don’t specify a value, the default is 3 months. The value of the field is a numeric string followed by the character “s”, for example “86400s” for one day, or “604800s” for one week.

Only applies to DATE fields.

RankOrder -> (string)

Determines how values should be interpreted.

When the RankOrder field is ASCENDING , higher numbers are better. For example, a document with a rating score of 10 is higher ranking than a document with a rating score of 1.

When the RankOrder field is DESCENDING , lower numbers are better. For example, in a task tracking application, a priority 1 task is more important than a priority 5 task.

Only applies to LONG and DOUBLE fields.

ValueImportanceMap -> (map)

A list of values that should be given a different boost when they appear in the result list. For example, if you are boosting a field called “department,” query terms that match the department field are boosted in the result. However, you can add entries from the department field to boost documents with those values higher.

For example, you can add entries to the map with names of departments. If you add “HR”,5 and “Legal”,3 those departments are given special attention when they appear in the metadata of a document. When those terms appear they are given the specified importance instead of the regular importance for the boost.

key -> (string)

value -> (integer)

Search -> (structure)

Provides information about how the field is used during a search.

Facetable -> (boolean)

Indicates that the field can be used to create search facets, a count of results for each value in the field. The default is false .

Searchable -> (boolean)

Determines whether the field is used in the search. If the Searchable field is true , you can use relevance tuning to manually tune how Amazon Kendra weights the field in the search. The default is true for string fields and false for number and date fields.

Displayable -> (boolean)

Determines whether the field is returned in the query response. The default is true .

Sortable -> (boolean)

Determines whether the field can be used to sort the results of a query. If you specify sorting on a field that does not have Sortable set to true , Amazon Kendra returns an exception. The default is false .

IndexStatistics -> (structure)

Provides information about the number of FAQ questions and answers and the number of text documents indexed.

FaqStatistics -> (structure)

The number of question and answer topics in the index.

IndexedQuestionAnswersCount -> (integer)

The total number of FAQ questions and answers contained in the index.

TextDocumentStatistics -> (structure)

The number of text documents indexed.

IndexedTextDocumentsCount -> (integer)

The number of text documents indexed.

IndexedTextBytes -> (long)

The total size, in bytes, of the indexed documents.

ErrorMessage -> (string)

When the Status field value is FAILED , the ErrorMessage field contains a message that explains why.

CapacityUnits -> (structure)

For Enterprise Edition indexes, you can choose to use additional capacity to meet the needs of your application. This contains the capacity units used for the index. A query or document storage capacity of zero indicates that the index is using the default capacity. For more information on the default capacity for an index and adjusting this, see Adjusting capacity .

StorageCapacityUnits -> (integer)

The amount of extra storage capacity for an index. A single capacity unit provides 30 GB of storage space or 100,000 documents, whichever is reached first.

QueryCapacityUnits -> (integer)

The amount of extra query capacity for an index and GetQuerySuggestions capacity.

A single extra capacity unit for an index provides 0.1 queries per second or approximately 8,000 queries per day.

GetQuerySuggestions capacity is five times the provisioned query capacity for an index, or the base capacity of 2.5 calls per second, whichever is higher. For example, the base capacity for an index is 0.1 queries per second, and GetQuerySuggestions capacity has a base of 2.5 calls per second. If you add another 0.1 queries per second to total 0.2 queries per second for an index, the GetQuerySuggestions capacity is 2.5 calls per second (higher than five times 0.2 queries per second).

UserTokenConfigurations -> (list)

The user token configuration for the Amazon Kendra index.

(structure)

Provides the configuration information for a token.

JwtTokenTypeConfiguration -> (structure)

Information about the JWT token type configuration.

KeyLocation -> (string)

The location of the key.

URL -> (string)

The signing key URL.

UserNameAttributeField -> (string)

The user name attribute field.

UserNameAttributeField -> (string)

The user name attribute field.

The group attribute field.

UserContextPolicy -> (string)

The user context policy for the Amazon Kendra index.

UserGroupResolutionConfiguration -> (structure)

Shows whether you have enabled the configuration for fetching access levels of groups and users from an Amazon Web Services Single Sign On identity source.

UserGroupResolutionMode -> (string)

The identity store provider (mode) you want to use to fetch access levels of groups and users. Amazon Web Services Single Sign On is currently the only available mode. Your users and groups must exist in an Amazon Web Services SSO identity source in order to use this mode.
