# DREQuery

An HPE IDOL Server query to determine the results set to use to generate the taxonomy.

Allows you to submit a query to HPE IDOL Server and generate a taxonomy from the results that this query produces. The query can be one of the following:

- Free query text. To run a simple query without specifying any restrictions, you can type only the query text. For example:

      DREQuery=citrus fruit

- Full query syntax. To run a complex query, you can use the normal Query syntax format (refer to the HPE IDOL Server Administration Guide). If you send the action by using an HTTP query, you must percent-encode the query string. Otherwise (for example, if you use a scheduled operation) you do not need to percent-encode it. For example:

      DREQuery=action%3DQuery%26Text%3Dcitrus%20fruit%26MinScore%3D60

Actions: | TaxonomyGenerate

Example: |
    DREQuery=action%3DQuery%26Text%3Dsport%26MaxResults%3D5000%26DatabaseMatch%3DNews%20Sports%26MinDate%3D%2D7
In this example, HPE IDOL Server returns up to 5,000 documents about sport that were indexed into the `News` and `Sports` databases within the last seven days. HPE IDOL Server generates a taxonomy from the results.
