IDOL Server 24.2

# FieldStats

Set `FieldStats` to `True` to return statistics in the attributes for the fields that return.

This parameter has an effect only if you have enabled CollectFieldStatistics in your index, and if statistics data is available.

When your IDOL index contains field statistics data, setting this parameter to `True` returns information about the occurrences of structured field and value pairs, and how they characterize the selected documents. The field statistics information returns in the `<autn:structured>` section of the XML response. For example:

    <autn:structured>
       <autn:number_of_field_values>16</autn:number_of_field_values>
       <autn:field_value field="DOCUMENT/COLOUR" apcm_weight="254" document_occurrences="1" total_occurrences="1" fieldtype="3">blue</autn:field_value>
       <autn:field_value field="DOCUMENT/COUNTRY" apcm_weight="254" document_occurrences="1" total_occurrences="1" fieldtype="3">Germany</autn:field_value>
       <autn:field_value field="DOCUMENT/DEALER" apcm_weight="254" document_occurrences="1" total_occurrences="1" fieldtype="3">Hertz</autn:field_value>
    ...
    </autn:structured>
