See ‘aws help’ for descriptions of global parameters.

Synopsis

  define-expression
--domain-name <value>
--expression <value>
--name <value>
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]
[--cli-auto-prompt <value>]

Options

--domain-name (string)

A string that represents the name of a domain. Domain names are unique across the domains owned by an account within an AWS region. Domain names start with a letter or number and can contain the following characters: a-z (lowercase), 0-9, and - (hyphen).

--expression (string)

The expression to evaluate for sorting while processing a search request. The Expression syntax is based on JavaScript expressions. For more information, see Configuring Expressions in the Amazon CloudSearch Developer Guide .

--name (string)

Names must begin with a letter and can contain the following characters: a-z (lowercase), 0-9, and _ (underscore).

--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.

--cli-auto-prompt (boolean) Automatically prompt for CLI input parameters.

See ‘aws help’ for descriptions of global parameters.

Output

Expression -> (structure)

The value of an Expression and its current status.

Options -> (structure)

The expression that is evaluated for sorting while processing a search request.

ExpressionName -> (string)

Names must begin with a letter and can contain the following characters: a-z (lowercase), 0-9, and _ (underscore).

ExpressionValue -> (string)

The expression to evaluate for sorting while processing a search request. The Expression syntax is based on JavaScript expressions. For more information, see Configuring Expressions in the Amazon CloudSearch Developer Guide .

Status -> (structure)

The status of domain configuration option.

CreationDate -> (timestamp)

A timestamp for when this option was created.

UpdateDate -> (timestamp)

A timestamp for when this option was last updated.

UpdateVersion -> (integer)

A unique integer that indicates when this option was last updated.

State -> (string)

The state of processing a change to an option. Possible values:

• RequiresIndexDocuments : the option’s latest value will not be deployed until IndexDocuments has been called and indexing is complete.

• Processing : the option’s latest value is in the process of being activated.

• Active : the option’s latest value is completely deployed.

• FailedToValidate : the option value is not compatible with the domain’s data and cannot be used to index the data. You must either modify the option value or update or remove the incompatible documents.

PendingDeletion -> (boolean)

Indicates that the option will be deleted once processing is complete.
