# Customize Document Processing

You can add the following fields to a document to control how the document is processed by CFS. Unless stated otherwise, you can add the fields with any value.

## AUTN_FILTER_META_ONLY

Prevents KeyView extracting file content from a file. KeyView only extracts metadata and adds this information to the document.

## AUTN_NO_FILTER

Prevents KeyView extracting file content and metadata from a file. You can use this field if you do not want to extract text from certain file types.

## AUTN_NO_EXTRACT

Prevents KeyView extracting subfiles. You can use this field to prevent KeyView extracting the contents of ZIP archives and other container files.

## AUTN_NEEDS_IMAGE_SERVER_ANALYSIS

Identifies images that you want to send to Image Server for image analysis, using an `ImageServerAnalysis` import task. You do not need to add this field if you are using a Lua script to run image analysis. Image Server enriches documents that represent images by running operations such as optical character recognition, face recognition, and object detection. For more information about running analysis on images, refer to the Connector Framework Server Administration Guide.

## AUTN_NEEDS_VIDEO_SERVER_ANALYSIS

Identifies video that you want to send to Video Server for analysis, using a `VideoServerAnalysis` import task. You do not need to add this field if you are using a Lua script to run video analysis. For more information about running analysis on video, refer to the Connector Framework Server Administration Guide.

## AUTN_NEEDS_TRANSCRIPTION

Identifies audio and video assets that you want to send to an IDOL Speech Server for speech-to-text processing, using an `IdolSpeech` import task. You do not need to add this field if you are using a Lua script to run speech-to-text. For more information about running speech-to-text on documents, refer to the Connector Framework Server Administration Guide.

## AUTN_FORMAT_CORRECT_FOR_TRANSCRIPTION

To bypass the transcoding step of an `IdolSpeech` import task, add the field `AUTN_FORMAT_CORRECT_FOR_TRANSCRIPTION`. Documents that have this field are not sent to a Transcode Server. For more information about the `IdolSpeech` task, refer to the Connector Framework Server Administration Guide.

## AUTN_AUDIO_LANGUAGE

To bypass the language identification step of an `IdolSpeech` import task add the field `AUTN_AUDIO_LANGUAGE`. The value of the field must be the name of the IDOL Speech Server language pack to use for extracting speech. Documents that have this field are not sent to the IDOL Speech Server for language identification. For more information about the `IdolSpeech` task, refer to the Connector Framework Server Administration Guide.
