# TaxonomyGenerate

Allows you to generate a hierarchical taxonomy from a cluster, or from a set of query results.

NOTE: This is an administrative action that can be sent only by users that belong to an authorization role that allows the `Admin` standard role, or which enables the action explicitly. See Authorization Roles Configuration Parameters.

To generate a taxonomy from a set of query results, you must set DREQuery. To generate a taxonomy from a cluster, you must set Cluster and SourceJobName.

You can use the WriteTaxonomy parameter to specify whether to write the taxonomy to disk or to add the taxonomy to your category hierarchy.

If you write the taxonomy to disk, the Category component stores it as a folder hierarchy in the `HIERDOCS` subdirectory in the `taxonomy` directory of your Category installation. It stores the taxonomy documents in text format. Otherwise, Category adds the taxonomy to the position in the category hierarchy that you specify with the Parent parameter.

NOTE: Before you create a taxonomy from Category, you must make sure that it does not contain duplicate documents or text that is repeated in multiple documents (for example, document headers). Ensure that these are stripped out at the import stage to gain optimal results.

## Example

    http://12.3.4.56:9020/action=TaxonomyGenerate&Parent=123456789987654321&DREQuery=new+tax+cuts

This action sends the query new tax cuts to Category. Category uses the results of this query to generate a taxonomy, which it adds to the category hierarchy as a child of the category with the ID `123456789987654321`.
