# DREADDDATA

NOTE: This index action requires a POST request method. For details on how to use a POST request method, refer to the Knowledge Discovery Administration Guide.

Allows you to index data over a socket into a Content component. Use this index action if the data is not accessible by the Content components that you are indexing into. Parameters that you use with `DREADDDATA` override any equivalent settings in the Content configuration file.

You specify the data to index in the POST data (see Data).

NOTE: If your Content configuration file does not contain a field process to allow it to read the destination databases from a document field, you must also specify either DREDbName or DatabaseFields.

You can choose a deduplication option either by setting the KillDuplicates index action parameter, or by adding your KillDuplicatesOption directly to the end of the `#DREENDDATA` string in your POST request. If you do not set either option, Content uses the value of the `KillDuplicates` configuration parameter.

If you have set DelayedSync to `True` or you have set a high MaxSyncDelay in the configuration file, some time might elapse before a file is available for query.

NOTE: The request body must end with a blank line (`\r\n\r\n`)

## Examples

The following examples show a HTTP request performing a `DREADDDATA` index action.

Example 1:

    POST /DREADDDATA?LanguageType=EnglishUTF8 HTTP/1.0
    Content-Length: 604
    #DREREFERENCE 392348A0
    #DREFIELD authorname1="Brown"

    #DREFIELD title="Dr."
    #DREDATE 1998/08/06

    Jurassic Molecules
    #DRECONTENT
    Using a technique called test tube evolution, scientists created a nucleic acid enzyme, the first known enzyme that uses an amino acid to start chemical activity. Scientists hope that the creation of this molecule will lead to the elusive precursor. The precursor, by definition, will have to contain both the genetic code for replication and an enzyme to trigger self replication.

    POST /DREADDDATA?DREDbName=Poetry&DateFields=*/Date HTTP/1.0

    <DRECONTENT>
    You love the roses - so do I. I wish
    The sky would rain down roses, as they rain
    From off the shaken bush. Why will it not?
    Then all the valley would be pink and white
    And soft to tread on. They would fall as light
    As feathers, smelling sweet; and it would be
    Like sleeping and like waking, all at after!

    </DOCUMENT>
